OBJECTIVE: While an echogenic intracardiac focus (EIF) is associated with an increased risk of trisomy 21 (T21), the magnitude of that risk remains controversial, particularly in the setting of a low-risk triple screen (TS). The objective of this study is to define the risk of T21 in patients with a low-risk TS and an isolated EIF. STUDY DESIGN: A retrospective analysis was performed on patients presenting prior to 22 6/7 weeks of gestation. Patients met criteria for inclusion if an EIF was noted, a TS had been drawn, the anatomic survey was complete and was determined to be normal, and karyotyping or delivery occurred at Bellevue Hospital. A high-risk TS was defined as a risk of <1:500, assuming a 2-fold increased risk in the setting of an isolated EIF. A low-risk TS was defined as a risk of >1:500. Statistical analysis was performed using chi-square, with p values of <0.05 considered significant. RESULTS: 7,318 anatomic surveys were performed. An EIF was identified in 584 patients (7.98%), of which 391 met the criteria for inclusion. Of the 391, 51% were Asian and 38% were Hispanic; 348 had a low-risk TS and 43 had a high-risk TS. Patients with an EIF and a low-risk TS had a significantly lower risk of having a T21 pregnancy compared to those with a high-risk TS and an EIF (0 vs. 2.3%; p = 0.004). CONCLUSION: An isolated EIF with a low risk TS is not associated with an increased risk of T21.

Reassuring Article About Echogenic Intracardiac Focus
Relationship of isolated fetal intracardiac echogenic focus to trisomy 21 at the mid-trimester sonogram in women younger than 35 years.

OBJECTIVE: To determine whether an isolated echogenic intracardiac focus in the fetal heart in the mid-trimester (16-24 weeks) in women aged 18-34 years of age is associated with trisomy 21. METHOD: This was a prospective population-based observational study. A search of all obstetric sonograms performed in our region from January 1997 to December 1999 was carried out. From 12,373 pregnancies we identified 267 cases of echogenic foci in the fetal heart. Trisomy 21 was detected in 38 deliveries (0.31%). An echogenic focus was seen in 193 of the 9167 women < 35 years of age who had an obstetric sonogram at 16-24 weeks' gestation, and an echogenic focus was seen in 67 of the 1968 women > 35 years. The study group comprised the 149 women aged 18-34 years who had an echogenic focus in the fetal heart as the only abnormality at an obstetric sonogram performed at 16-24 weeks' gestation. RESULTS: There were no abnormal outcomes or cases of trisomy 21 among the 149 pregnancies with an echogenic focus as an isolated finding in women aged 18-34 years (0% (95% confidence interval, 0.00-2.43)). The prevalence of isolated echogenic focus was 1.6% for women < 35 and 1.8% for women >or= 35 years old. Of the 25 fetuses with trisomy 21 undergoing an obstetric sonogram at any gestational age, five (20%) had an echogenic focus. An isolated echogenic focus was present in one fetus with trisomy 21 seen at 26 weeks' gestation in a 17-year-old mother. Echogenic foci were single and in the left ventricle in 84.7% of cases. CONCLUSION: An isolated echogenic focus in the fetal heart at mid-trimester ultrasound in women aged 18-34 years is not associated with increased risk for trisomy 21. Copyright 2003 ISUOG.

Even Better News!
I am officially 21 weeks today! Woohoo! I am more than halfway done with this pregnancy, no matter when I deliver.
Before I forget, I wore my first official maternity outfit to work last wednesday at 20 weeks. I got a lot of compliments on it. At home, I can still wear sweats, but I am transitioning more and more into maternity clothes.
I have more updates about our LO's condition. I finally was able to speak to my OB yesterday. The perinatologist does not believe that I have vasa previa. Instead, he thinks the veins are at the top of the placenta so that there is a buffer between the veins and the cervix. This is really, really good news.
Also, my activity level has not been changed - still just pelvic rest. No bedrest or hospital bedrest. This is huge for me!!
I will also be getting another ultrasound at 23 weeks (May 14th), so that will be cool.
Lastly, apparently, there is some shortening of our son's femur(s), but nothing that is considered abnormal. We started the referral for the amnio, but we are going to wait until I am further along - in case something happens during the amnio.
so, we are starting to get more reassuring news.

A Lot Has Happened Since Our Last Update!
On Wednesday (April 23rd), I began feeling a stabbing pain "down there". I called my doctor, who asked me to come for a cervical examination immediately. I was so nervous, but everything is good. My cervix is long, closed and thick. We also got to hear the baby's heartbeat, so that was reassuring. I was also exactly 20 weeks.
On Friday (April 25th), I went for my Level 2 ultrasound. This test was supposed to reassure us about the vasa previa, but it did not do that. The perinatologist "does not think" I have vasa previa (what help is that???). He did note that the umbilical cord appears to have attached near my cervix, so that really does not reassure me. I will need more ultrasounds to monitor this (this recommendation has become a theme in my pregnancy).
The baby also has a choroid plexus cyst (CPC). Normally, these mean nothing and only 1% of pregnancies go on to have a baby born with a CPC. However, some pregnancies have an association between CPC and Down Syndrome or Trisomy 18 (fatal). The peri recommended an amnio, but i want to see what my OB says. Two weeks ago, my OB did not recommend the amnio, but things may have changed. Regardless, I need another ultrasound to monitor the progress.
With regards to the echogenic intracardic focus (another Down's marker), I will have a fetal echocardiogram on May 7th.
Then, the u/s tech and the peri seemed to think that I have more placenta previa than I did two weeks ago. Again, another u/s to monitor.
I'm still on pelvic rest, but no bedrest yet. My cervix is still nice and long, so that's reassuring. Then, I got a call later in the day that the report faxed to my OB said that I have vasa previa, so I am so confused.
On Friday and Sunday, two of Ashley's teeth broke through. On Friday, it was Ashley's top right and on Sunday, it was her top left tooth.

I've Been Such A Slacker Lately
Too much time has passed since my last post, and too many memories have passed. The most important news we have since my last post is that I am pregnant with our first son!!! Bryan and I are beyond thrilled about this. Unfortunately, we also got some potentially devestating news too. Three conditions were identified on my ultrasound: 1) increased echogenicity on the baby's heart, which can be a marker for Down's Syndrome. My doctor is not worried about this because the rest of the Down's testing (including my bloodwork, the baby's bone length, etc.) came back negative for Down's. So, all this means is that we are going to get another ultrasound to monitor the condition.
2) I have marginal placenta previa. Placenta previa is a condition where the placenta is close to, or on, the cervix. There are three types - complete, partial or marginal. Complete placenta previa means that the baby's placenta covers the mom's entire cervix, while marginal means that the placenta is right next to the cervix. There is a possibility that the placenta will move as my uterus grows, so, again, my doctor is not too worried. Again, I will be monitored by ultrasound to determine the status of the previa.
3) The most devestating news is that I might have vasa previa. This is a condition where the fetus' blood vessels stretch across my cervix. This is a potentially fatal condition for our son, as the babies bleed out relatively quickly once the mother goes into labor. I have a Level 2 ultrasound scheduled for Friday, April 25th to determine if there are fetal blood vessels over my cervix. If so, our whole plan of action changes. In the meantime, I am on pelvic rest and I have been told to take it easy until April 25th - no strenuous lifting, exercising and trying not to pick up Ashley too much.
In other news, Ashley cut her first upper tooth today. The tooth is one of her front teeth, on the right side. Otherwise, she continues to do well. She is babbling like crazy, cruising like a madwoman and being overall cute. She is more and more interested in table food and not baby food anymore. She's been in a relatively good mood and a good sleeper through her teething. She's just the best baby anyone could possibly ask for.

Our Miracle, A Year Later...
A year ago, Bryan and I were in an unimaginable and unenviable position - we were the proud, scared, thrilled, emotional parents of a newborn baby. The only problem? Our baby was not supposed to be born in March. She was not supposed to be born in April or May either. Her EDD was June 16, 2007, which made Ashley 11w6d early.
Our ordeal began on March 19, 2007. I was 2 cm dilated and 80% effaced. By 7 am on the morning of the 20th, I was 7 cm dilated. The entire staff at St. Joseph Mercy Hospital - Pontiac thought we would have Ashley on the 20th. My attending OB that day brought in the director of the NICU to brief us. I knew most of the problems that Ashley could face (periventricular leukomalacia, intraventricular hemmorhage, retinopathy of prematurity, cerebral palsy, hydrocephalus, mental retardation, etc.) simply from my employment as a medical malpractice attorney. Bryan, luckily, or unluckily (depending upon how you look at it), did not know as much.
However, we both had the same reaction that morning, tears were streaming down our face. I remember thinking, "this is not supposed to happen to us." I had the perfect pregnancy, up until March 19th. No complications, no abnormal blood pressure, nothing. I ate perfectly, watched what I was supposed to consume, limited my caffeine intake and exercised. I was the last person in the world that I expected this to happen to. But, what could I do? Bryan and I were told to start praying that the baby was a girl, because white girls do much better than white boys in the NICU (we did not learn the sex until Ashley was born). We were also told to pray that I make it to 28 weeks, because there is an 80% survival rate at that point. We prayed like crazy!
For reasons completely unknown to me, my body cooperated until Sunday, March 25th. I was exactly 28w1d at that point. My contractions began picking up again around 5:30 p.m. or 6:00 p.m. Bryan was at home taking care of some business (he had been a dear and was staying overnight at the hospital with me). I called him back to the hospital immediately. Approximately 3 hours later, at 8:32 p.m., after 10-15 minutes of pushing, Ashley was born. She weighed 2 pounds, 8.2 oz and was 14 inches long. Much to my surprise, she cried! I think that was the best sound I could have possibly heard. The NICU staff was present during the delivery and immediately began to stabilize/assess her. I was able to hold her for a few minutes before she was whisked away to the NICU.
Those next few hours were horrible. Everyone left my room shortly after Ashley did. I showered with the assistance of a nurse, then was whisked away to my post-partum room. I got to visit Ashley, which was surreal. She was so tiny and perfect. However, she was hooked up to an IV, oxygen, etc. This is not what I pictured my post-operative experience to be. We got to visit for about a half hour, then I went back to my room. This was a very lonely experience. I decided to breastfeed, so I had a breast pump delivered to my room. I had to wake myself up every 2-3 hours around the clock to pump, but my baby was no where in sight. That was pretty depressing. I could hear babies crying in the hallway, which depressed me even more.
The worst experience of my life, to date, was when I left the hospital without my baby, I almost cried. I would never wish that upon anyone. No mother should have to leave the hospital without her baby. Ashley was relatively stable, but Bryan and I were ever cognizant of the fact that something dire could happen at a moment's notice. When I left the hospital, it was no guarantee that Ashley would make it to the next day. I really did not want to leave, but my insurance would not let me stay.
I visited Ashley twice a day until she came home - 46 days later. Bryan would see her every day as well. We got to change her diaper, take her temperature, bathe her, hold her and, eventually, feed her by bottle. We lived for these moments. We never let the staff bathe Ashley, after we got the okay to do it. These small assistances allowed us to be a part of Ashley's daily life. We got to be parents for a short amount of time. Just like my pumping at home, we were a part of her care.
Ashley came home on May 10th on oxygen and a heart monitor. This was a scary experience. The heart monitor would beep if Ashley stopped breathing or if her heart stopped beating. Quite a few times, the alarm attached to the machine went off in the middle of the night, and both Bryan and I would sit bolt right up in bed and run to her bassinet! A couple of times, Ashley did stop breathing, but she always came back (another preemie complication). We finally got rid of the oxygen on June 15th and the heart monitor in July. Thank goodness!
Luckily for us, Ashley grew really well throughout her first year. We never had a set back and all of our developmental appointments came back with flying colors. We have never needed physical therapy, occupational therapy, speech therapy, or Early On. We have also only had to experience one cold - no fevers, RSV, ear infections, breathing problems, etc. We have been very, very lucky. We realize that not all preemie parents can say this, even parents of preemies born later than Ashley. We are well aware of what could have happened, and how different our lives could be. We were prepared for multiple specialist appointments, but we never have had to do this.
All we can do is be thankful to God. We firmly believe that my grandfather and Bryan's grandmother have been watching out for Ashley. She is truly a gift from God, as is her development, her milestones, her abilities, her personality, etc. We could not have asked for a better experience, and we are ever cognizant that another pregnancy could turn out completely different than this one. The fact that Ashley is developing along the lines of a normal one year old is just amazing to us. She is so smart and engaging, something that we were prepared for might never happen. We do not know why we were blessed this way, but we continue to thank God for this blessing.
We are forever proud to be Ashley's parents. I am firmly convinced that we had Ashley as a preemie so that we would not take life for granted. Most parents take their child's development, discoveries, abilities, etc. for granted. They compete for each other for the title of first smile, first crawl, etc. When Ashley was born, nothing was guaranteed. We did not know if she would smile, if she would talk, if she would stand, crawl, etc. We did not know how her prematurity would affect her. Each thing that Ashley has done has been a miracle for us. We celebrate everything that Ashley does because there was no guarantee. Her prematurity has taught us to be grateful for everything life offers us and we would not change it for the world.
Thank you Ashley for choosing us to be your parents! We absolutely love you princess and we are soooooo immensely proud of you. You have been a blessing and everything we could possibly hope for. Happy First Birthday Sweetie! We look forward to celebrating more birthdays with you.

Alot Has Happened Since My Last Post
If you notice, the date of my last post was Ashley's 1 year birthday. I have been hesitant to post on here because I do not know what to say, yet I have a lot to say. I'll update on the most recent events in our lives, then devote an entire post to Ashley's one year birthday.
Our first update occurred on March 28th. This was Ashley's last RSV shot and her 1 year well baby appointment. She weighed 19 pounds, 12.5 oz and was 28.25 inches long. This is the 25th percentile for both measurements, which is consistent with her growth pattern since May of 2007. We got the go ahead at this appointment to make the switch to whole milk (which was good because we had been mixing the frozen breastmilk and whole milk together). Ashley did not enjoy her last RSV shot, but, hopefully, she will never need the shots again. They did a wonderful job protecting her this past winter, so they were a necessary evil. She also began eating Velveeta shells and cheese, and she LOVES it! In fact, I cannot eat first - Ashley must receive all macaroni before mommy.
On Saturday night (March 29th), I think I felt the "new" baby moving for the first time. This is much earlier than I felt Ashley, but apparently this is common in subsequent pregnancies. I was 16w3d at this point. The baby felt like little bubbles popping in my stomach. It is so hard to describe, unless you have been pregnant, then you know exactly what I am talking about. Today, I felt the baby move a lot more after dinner - around 7 pm. The movements are not consistent yet, they come, then they go. I have not tried to get Bryan to feel them yet, because they are so fleeting. In the next few weeks, this baby will get so much more strong. I cannot wait to feel those kicks.
If you have read my previous posts, you will see that Ashley has begun pulling herself up on objects. Over the past week, she has become more agile and adept at pulling up. Well, Ashley has advanced even more in this area. On Sunday, March 30th, Ashley was standing up in her crib. This is a first for her. Bryan walked in her room and could not believe it. Today, we finally lowered the crib (especially after my mom told me that she had pulled up again). This was a milestone for me because it signals the fact that Ashley is no longer a baby. We will never go back in time with her. From this point forward, she is a big girl. I just saw her in her lowered crib and I cannot believe it - my baby is growing up.
I had my second 17P injection on Monday, the 31st. Again, reading my previous posts, you see the reason for the injection. I have to receive the injection on the same day every week. The shot goes in one of my buttocks, and we alternate each week. Surprisingly, the shot does not hurt. There are some side effects, such as fatigue, headaches and breakthrough bleeding. I think the only side effect I am experiencing is the fatigue. I feel so tired still - like I am still in my first trimester. However, I will do whatever I need to so that this pregnancy makes it to 37 weeks, at least.
Our last tidbit of news is that Ashley ate at Mongolian BBQ last night with us. This is one of our favorite restaurants. She sat in her highchair patiently and allowed us to feed her bits of chicken, potato, lamb and egg. She really seemed to enjoy herself. However, every once in a while, she experienced some of the sauce and seasonings, which she really has never had before (all her food is pretty bland). She would scrunch her face up and stick out her tongue like we were poisoning her. She's so adorable, though, and such a trooper. She really, really loves adult food.
Our first update occurred on March 28th. This was Ashley's last RSV shot and her 1 year well baby appointment. She weighed 19 pounds, 12.5 oz and was 28.25 inches long. This is the 25th percentile for both measurements, which is consistent with her growth pattern since May of 2007. We got the go ahead at this appointment to make the switch to whole milk (which was good because we had been mixing the frozen breastmilk and whole milk together). Ashley did not enjoy her last RSV shot, but, hopefully, she will never need the shots again. They did a wonderful job protecting her this past winter, so they were a necessary evil. She also began eating Velveeta shells and cheese, and she LOVES it! In fact, I cannot eat first - Ashley must receive all macaroni before mommy.
On Saturday night (March 29th), I think I felt the "new" baby moving for the first time. This is much earlier than I felt Ashley, but apparently this is common in subsequent pregnancies. I was 16w3d at this point. The baby felt like little bubbles popping in my stomach. It is so hard to describe, unless you have been pregnant, then you know exactly what I am talking about. Today, I felt the baby move a lot more after dinner - around 7 pm. The movements are not consistent yet, they come, then they go. I have not tried to get Bryan to feel them yet, because they are so fleeting. In the next few weeks, this baby will get so much more strong. I cannot wait to feel those kicks.
If you have read my previous posts, you will see that Ashley has begun pulling herself up on objects. Over the past week, she has become more agile and adept at pulling up. Well, Ashley has advanced even more in this area. On Sunday, March 30th, Ashley was standing up in her crib. This is a first for her. Bryan walked in her room and could not believe it. Today, we finally lowered the crib (especially after my mom told me that she had pulled up again). This was a milestone for me because it signals the fact that Ashley is no longer a baby. We will never go back in time with her. From this point forward, she is a big girl. I just saw her in her lowered crib and I cannot believe it - my baby is growing up.
I had my second 17P injection on Monday, the 31st. Again, reading my previous posts, you see the reason for the injection. I have to receive the injection on the same day every week. The shot goes in one of my buttocks, and we alternate each week. Surprisingly, the shot does not hurt. There are some side effects, such as fatigue, headaches and breakthrough bleeding. I think the only side effect I am experiencing is the fatigue. I feel so tired still - like I am still in my first trimester. However, I will do whatever I need to so that this pregnancy makes it to 37 weeks, at least.

Another OB Appointment
I went for my third OB appointment today. Everything looked great, which is always a relief. My doctor had a hard time finding the heartbeat, so I got an extra ultrasound "just to make sure." I got to see our LO moving all around. I could never, ever get tired of that image. I also got my first 17 alpha hydroxyprogesterone injection. This is the injection that Bryan and I praying allows me to make it to 36 weeks, at least. I am supposed to get the shot weekly (on the same day) from 16 weeks to 36 weeks. Below is why this shot is so important to us:

ABSTRACT
Background Women who have had a spontaneous preterm delivery are at greatly increased risk for preterm delivery in subsequent pregnancies. The results of several small trials have suggested that 17 alpha-hydroxyprogesterone caproate (17P) may reduce the risk of preterm delivery.
Methods
We conducted a double-blind, placebo-controlled trial involving pregnant women with a documented history of spontaneous preterm delivery. Women were enrolled at 19 clinical centers at 16 to 20 weeks of gestation and randomly assigned by a central data center, in a 2:1 ratio, to receive either weekly injections of 250 mg of 17P or weekly injections of an inert oil placebo; injections were continued until delivery or to 36 weeks of gestation. The primary outcome was preterm delivery before 37 weeks of gestation. Analysis was performed according to the intention-to-treat principle.
Results
Base-line characteristics of the 310 women in the progesterone group and the 153 women in the placebo group were similar. Treatment with 17P significantly reduced the risk of delivery at less than 37 weeks of gestation (incidence, 36.3 percent in the progesterone group vs. 54.9 percent in the placebo group; relative risk, 0.66 [95 percent confidence interval, 0.54 to 0.81]), delivery at less than 35 weeks of gestation (incidence, 20.6 percent vs. 30.7 percent; relative risk, 0.67 [95 percent confidence interval, 0.48 to 0.93]), and delivery at less than 32 weeks of gestation (11.4 percent vs. 19.6 percent; relative risk, 0.58 [95 percent confidence interval, 0.37 to 0.91]). Infants of women treated with 17P had significantly lower rates of necrotizing enterocolitis, intraventricular hemorrhage, and need for supplemental oxygen.
Conclusions
Weekly injections of 17P resulted in a substantial reduction in the rate of recurrent preterm delivery among women who were at particularly high risk for preterm delivery and reduced the likelihood of several complications in their infants.
Preterm delivery — that is, delivery before 37 completed weeks of gestation — is the major determinant of infant mortality in developed countries. Preterm delivery is more common in the United States than in many other developed countries and is the factor most responsible for the relatively high infant mortality in this country. The rate of preterm delivery in the United States has increased progressively from 9 percent to 12 percent over the past two decades. Despite many trials of reduced activity, tocolytic therapy, antibiotic therapy, and other strategies for prevention, no effective and reproducible method of preventing preterm delivery has been demonstrated.
One treatment that showed promise in small trials was prophylactic treatment with progestational compounds. Not all trials reported positive results. One meta-analysis found no evidence of effectiveness of progestational compounds in the prevention of preterm delivery or the prevention of recurrent miscarriage. Another meta-analysis, restricted to trials of 17 alpha-hydroxyprogesterone caproate (17P), a natural metabolite of progesterone, showed, in composite, a significant reduction in the rate of preterm delivery. We therefore chose this pharmacologic agent as the active drug for our study.
Women who have had a preterm delivery are at especially high risk for preterm delivery in a subsequent pregnancy. We therefore conducted a multicenter trial to test the effectiveness of 17P as compared with placebo in the prevention of recurrent preterm delivery in this group of women.
Methods
Subjects and Screening
Medical records of women presenting for prenatal care at the 19 participating centers were screened for eligibility to participate in the trial; criteria for eligibility included a history of spontaneous preterm delivery in a previous pregnancy and a current pregnancy between 15 weeks and 20 weeks 3 days of gestation. Reasons for exclusion were multifetal gestation, known fetal anomaly, progesterone or heparin treatment during the current pregnancy, current or planned cervical cerclage, hypertension requiring medication, a seizure disorder, or a plan to deliver elsewhere. An ultrasonographic examination was required between 14 weeks and 20 weeks 6 days of gestation to confirm the duration of gestation and to identify any major fetal anomalies. The duration of gestation at the time of randomization was determined according to a previously described algorithm on the basis of the last menstrual period and the results of ultrasonography.
Candidates for the trial were approached by a research nurse, who explained the study and asked prospective participants to sign a form for the release of medical records to permit the research nurse to obtain a copy of the chart from the previous pregnancy ending in preterm delivery. If the previous preterm delivery was of a liveborn singleton infant between 20 weeks of gestation and 36 weeks 6 days of gestation and was due to spontaneous preterm labor or preterm premature rupture of the fetal membranes, and if no criteria for exclusion were present, the woman was deemed to be eligible for the study. Each eligible woman was then invited to participate and to sign a consent form approved by the local institutional review board.
The trial started in April 1998 but was stopped in February 1999 because the Food and Drug Administration had ordered the pharmaceutical company that supplied the active study drug to shut down and had mandated a total recall of all the company's drugs, including the study drug, because of poor quality control and documentation. Patient safety was not considered to have been compromised, but the potency of the product that had been supplied was thought to be questionable. At the time the study was stopped, 150 women had been enrolled, but none of the data had been analyzed. The trial was started anew with the study drug and placebo supplied by a company that manages investigational drugs (Eminent Services), and the data that had been collected previously were not included in the analyses.
Randomization and Follow-Up Visits
Consenting women were given a trial intramuscular injection of the inert oil placebo and asked to return in one week for randomization. If a woman did not return for a randomization visit between 16 weeks and 20 weeks 6 days of gestation, she was not permitted to participate in the trial. Returning eligible patients were then assigned to receive identically appearing active (17P) or placebo (castor oil) injections prepared by a research pharmacy. The women, their caregivers, and research personnel were not informed of the study-group assignment.
The boxes of 17P or placebo were packaged for each center according to a randomization sequence prepared by the George Washington University Biostatistical Coordinating Center. The urn method of randomization, with stratification according to clinical center, was used to create the computer-generated randomization sequence. A 2:1 ratio was used for the assignment of women to 17P or to placebo, because it was known that patients assigned to placebo would be receiving painful injections on a weekly basis with no possibility of direct benefit.
After entering the study, the subjects returned for weekly injections of 17P or placebo given by a study nurse; the injections continued until 36 weeks of gestation or delivery, whichever occurred first. In addition to the weekly visits for study injections, the women received prenatal care at their institutions, as judged appropriate by their caregivers for their known level of risk of preterm delivery.
Assessment of Outcome
After delivery, study personnel reviewed all prenatal, delivery, newborn, and postpartum records and documented the date of delivery, birth weight of the infant, and neonatal course, as well as the occurrence of complications of pregnancy. Infants were followed until discharge from the hospital where they were born or, if they were transferred elsewhere, from the hospital to which they were transferred. Preterm delivery was defined as delivery at less than 37 completed weeks (259 days) of gestation, calculated as delineated above.
Statistical Analysis
The analysis was performed according to the intention-to-treat principle. Continuous variables were compared with the use of the Wilcoxon rank-sum test, and categorical variables were compared with the use of the chi-square or Fisher's exact test (the latter when there was an expected value of less than five for any cell). Prolongation of pregnancy was assessed by life-table methods, with the duration considered being that between the time of randomization and the time a woman gave birth, was lost to follow-up, or reached 40 weeks of gestation, whichever came first. Curves for event-free survival were estimated with use of the Kaplan–Meier method, with adjustment to account for differing durations of gestation at entry, and were tested with the log-rank test.
On the basis of data from a previous study by the Maternal–Fetal Medicine Units Network,we estimated that 37 percent of the women in the placebo group would deliver before 37 weeks of gestation. With the use of this estimate, a total sample size of 500 women (334 in the progesterone group and 166 in the placebo group) was deemed to be sufficient for the detection of a reduction of 33 percent in the rate of preterm delivery (from 37 percent to 25 percent), under the assumptions of a type I error (two-sided) of 5 percent and a power of at least 80 percent. Before the study began, it was decided that the independent data and safety monitoring committee would use the group sequential method of Lan and DeMets, with a spending function for the type I error corresponding to the O'Brien–Fleming boundary, for interim monitoring and adjustment of the type I error. At the second interim analysis, conducted when 463 patients had undergone randomization, outcome data were available for 351 patients (70 percent of the planned sample). The boundary (P=0.015) for the test of significance of the primary outcome, preterm delivery, was found to have been crossed, and enrollment in the trial was halted.
Results
Characteristics of the Women
A total of 2980 women were identified as potentially eligible for the study on the basis of a review of medical records from September 1999 to February 2002. Of these women, 1039 were found to be eligible, and 463 eligible women gave consent for the trial and underwent random assignment to 17P or placebo. The main reasons for ineligibility included lack of documentation of the qualifying preterm delivery (in the cases of 549 women), a gestational age of more than 20 weeks (482 women), and current or planned cervical cerclage (241 women).
The characteristics of the 310 women in the progesterone group and the 153 women in the placebo group are shown in Table1. The women in the two groups were similar in terms of the mean duration of gestation in the qualifying delivery, the mean duration of gestation at the time of randomization, race or ethnic group, marital status, body-mass index, educational level, smoking status, and substance use during pregnancy. The women in the placebo group had had more previous preterm deliveries (mean, 1.6 vs. 1.4; P=0.007).
Compliance and Side Effects
Noncompliance was defined by a gap of 10 days or more between any two injections. According to this definition, 91.5 percent of the women were compliant with all of their injections. There was no difference in the rate of compliance between the two groups. A total of 231 women (50 percent) reported at least one adverse effect. The most common side effects were local injection-site reactions, including soreness (in 34.2 percent of the women), swelling (in 14.1 percent), itching (in 11.3 percent), and bruising (in 6.7 percent). More women in the progesterone group than in the placebo group had swelling at the injection site (17.2 percent vs. 7.8 percent, P=0.007) or a lump at the injection site (5.5 percent vs. 1.3 percent, P=0.03).
Primary Outcome and Preterm Delivery
Outcome data were available for 459 of the 463 women (99.1 percent). The frequency of delivery before 37 weeks of gestation was 36.3 percent in the progesterone group, as compared with 54.9 percent in the placebo group (P<0.001). Delivery before 35 weeks of gestation was also less frequent in the progesterone group (20.6 percent vs. 30.7 percent, P=0.02). There was a 42 percent reduction in the rate of delivery before 32 weeks of gestation in the progesterone group (11.4 percent vs. 19.6 percent, P=0.02). Rates of preterm delivery in the progesterone group did not differ according to the week of gestation at the time of the qualifying delivery. Survival analysis showed a significant prolongation of pregnancy with 17P as compared with placebo (P=0.01). Because there was an imbalance between the progesterone and placebo groups with regard to the number of previous preterm deliveries, we performed an analysis with adjustment for this variable. The adjusted relative risk of delivery before 37 weeks of gestation in the 17P group as compared with the placebo group was 0.70 (95 percent confidence interval, 0.57 to 0.85). There were no significant differences between the two groups in the rates of hospital visits for preterm labor, use of tocolytic drugs, corticosteroid use, cesarean delivery, or chorioamnionitis.
Outcomes of Pregnancy According to Treatment Assignment.
More than half the women enrolled were black. The reduction in the rate of preterm delivery with 17P among the black women was very similar to that among nonblack women.
The effectiveness of 17P in this study suggests that only 5 to 6 women (95 percent confidence interval, 3.6 to 11.1) with a level of risk for preterm delivery similar to that among these women would need to be treated in order to prevent one preterm delivery before 37 weeks of gestation. Similarly, 12 women (95 percent confidence interval, 6.3 to 74.6) with a similar level of risk would need to be treated in order to prevent one delivery before 32 weeks of gestation.
Rates of spontaneous miscarriage between 16 weeks of gestation and 19 weeks 6 days of gestation, and rates of fetal death after 19 weeks 6 days of gestation are shown in Table 2 and Table 3. There was a small and nonsignificant increase in the rate of miscarriages and stillbirths in the progesterone group as compared with the placebo group. With one exception, all stillbirths occurred before 24 weeks of gestation.
Outcomes among the Infants
There was a significant reduction in the risk of a birth weight of less than 2500 g in the progesterone group as compared with the placebo group (relative risk, 0.66; P=0.003) and a nonsignificant reduction in the risk of a birth weight of less than 1500 g (relative risk, 0.62; P=0.08). Treatment with 17P led to significant reductions in the rates of necrotizing enterocolitis (P=0.01), need for supplemental oxygen, and intraventricular hemorrhage of any grade. However, there was no significant difference between groups in the rate of intraventricular hemorrhage of grade 3 to 4 specifically. The rates of infant death, transient tachypnea in the newborn, respiratory distress syndrome, bronchopulmonary dysplasia, need for ventilatory support, retinopathy of prematurity, and patent ductus arteriosus were slightly but not significantly lower in the progesterone group. Of the 17 neonatal deaths, 16 were due to complications of prematurity and 1 to intrapartum hypoxia subsequent to uterine rupture.
Nine of the infants were found to have congenital malformations (2.0 percent in each group). There was no consistent pattern to these defects, and none involved genital organs. One infant of a woman in the progesterone group had torsion of the testicles in utero, with subsequent infarction.
Discussion
Treatment with 17P on a weekly basis, beginning at 16 to 20 weeks of gestation and continued to delivery or 36 weeks of gestation, significantly reduced the rate of preterm delivery before 37 weeks, 35 weeks, and 32 weeks of gestation among women at high risk for preterm delivery. The rates of several complications of prematurity were correspondingly decreased among the infants of women assigned to this therapy.
The women enrolled in this study had high rates of preterm delivery, with more than 50 percent of the women who received the placebo injections delivering before 37 weeks of gestation. This high rate of preterm delivery is most likely related to the history of previous preterm deliveries. The earlier in a pregnancy a preterm delivery occurs, the greater the chance of preterm delivery in a subsequent pregnancy. In our study, the mean duration of gestation at the time of the qualifying delivery was 31 weeks, and a third of the women enrolled had had more than one previous preterm delivery. Therefore, the women in this study had particularly high risk. They were also strongly motivated, and compliance was excellent.
Preterm delivery has multiple causes. Some evidence suggests that the causes of early preterm delivery differ from those of later preterm delivery, with earlier preterm deliveries more often being related to infection. Whereas 17P would not be expected to affect an infectious process, in this study, it provided potent protection against early as well as later preterm delivery. The mechanisms of action of 17P in prolonging gestation are not entirely known. The actions of progesterone on the pregnant myometrium include relaxation of myometrial smooth muscle, blocking of the action of oxytocin, and inhibition of the formation of gap junctions. In sheep, goats, and some other mammals, a decrease in plasma progesterone and an increase in circulating estrogen precede the onset of labor. Although no such alteration in the ratio of plasma estrogen to progesterone precedes the onset of labor in primates, there is evidence that local changes in the progesterone level or the ratio of progesterone to estrogen in the placenta, decidua, or fetal membranes may be important in the initiation of labor in humans. In addition, administration of progesterone antagonists in women at term results in an increased rate of spontaneous labor.
We chose to use 17P because of reports of its effectiveness in some previous trials. Other studies showed no benefit, including a trial involving women with twin gestations and a trial in women with a low risk of preterm delivery. Most reported trials of other progesterone compounds have not demonstrated effectiveness in reducing the risk of preterm delivery. However, a recently reported trial in which progesterone suppositories were used suggested that this route of administration may be a viable alternative. The risk of preterm delivery was lower among participants in that study than among the women in our study. The entry criteria included a history of delivery before 37 weeks of gestation, cervical cerclage, or a uterine malformation. The women in the placebo group in that trial had a rate of preterm delivery of 28.5 percent as compared with 13.8 percent in the progesterone group. These results lend support to the concept of prophylactic use of progesterone to prevent preterm delivery.
Treatment with 17P also resulted in improved neonatal outcomes. Although the reduction in neonatal mortality in the progesterone group was not significant (relative risk, 0.44; P=0.08), the trial was not designed with sufficient power to address this end point adequately. There were significant reductions in the rates of necrotizing enterocolitis, any intraventricular hemorrhage, and the need for supplemental oxygen in the progesterone group.
17P appeared to be safe. There was no increase in the rate of congenital anomalies in the progesterone group. These results are consistent with surveys of the literature that have indicated an absence of teratogenic effects from the use of 17P during pregnancy.
The results of our trial should be interpreted with caution. Although 17P proved to be effective in preventing preterm delivery in our cohort of women at very high risk, it may not be effective in women with a lower risk of preterm delivery, and most preterm deliveries occur in women with no previous preterm delivery. Therefore, our results may not be generalizable to women whose risk factors for preterm delivery are different from those of the women in this trial. In addition, although 17P significantly reduced the rate of preterm delivery among the women who received it, the rate of preterm delivery in this group remained very high (36.3 percent). Thus, the identification of other causes of preterm delivery and other methods of preventing it remains a pressing need.

With the use of this estimate, a total sample size of 500 women (334 in the progesterone group and 166 in the placebo group) was deemed to be sufficient for the detection of a reduction of 33 percent in the rate of preterm delivery (from 37 percent to 25 percent), under the assumptions of a type I error (two-sided) of 5 percent and a power of at least 80 percent. Before the study began, it was decided that the independent data and safety monitoring committee would use the group sequential method of Lan and DeMets, with a spending function for the type I error corresponding to the O'Brien–Fleming boundary, for interim monitoring and adjustment of the type I error. At the second interim analysis, conducted when 463 patients had undergone randomization, outcome data were available for 351 patients (70 percent of the planned sample). The boundary (P=0.015) for the test of significance of the primary outcome, preterm delivery, was found to have been crossed, and enrollment in the trial was halted.
Results
Characteristics of the Women
A total of 2980 women were identified as potentially eligible for the study on the basis of a review of medical records from September 1999 to February 2002. Of these women, 1039 were found to be eligible, and 463 eligible women gave consent for the trial and underwent random assignment to 17P or placebo. The main reasons for ineligibility included lack of documentation of the qualifying preterm delivery (in the cases of 549 women), a gestational age of more than 20 weeks (482 women), and current or planned cervical cerclage (241 women).
The characteristics of the 310 women in the progesterone group and the 153 women in the placebo group are shown in Table1. The women in the two groups were similar in terms of the mean duration of gestation in the qualifying delivery, the mean duration of gestation at the time of randomization, race or ethnic group, marital status, body-mass index, educational level, smoking status, and substance use during pregnancy. The women in the placebo group had had more previous preterm deliveries (mean, 1.6 vs. 1.4; P=0.007).
Compliance and Side Effects
Noncompliance was defined by a gap of 10 days or more between any two injections. According to this definition, 91.5 percent of the women were compliant with all of their injections. There was no difference in the rate of compliance between the two groups. A total of 231 women (50 percent) reported at least one adverse effect. The most common side effects were local injection-site reactions, including soreness (in 34.2 percent of the women), swelling (in 14.1 percent), itching (in 11.3 percent), and bruising (in 6.7 percent). More women in the progesterone group than in the placebo group had swelling at the injection site (17.2 percent vs. 7.8 percent, P=0.007) or a lump at the injection site (5.5 percent vs. 1.3 percent, P=0.03).
Primary Outcome and Preterm Delivery
Outcome data were available for 459 of the 463 women (99.1 percent). The frequency of delivery before 37 weeks of gestation was 36.3 percent in the progesterone group, as compared with 54.9 percent in the placebo group (P<0.001). Delivery before 35 weeks of gestation was also less frequent in the progesterone group (20.6 percent vs. 30.7 percent, P=0.02). There was a 42 percent reduction in the rate of delivery before 32 weeks of gestation in the progesterone group (11.4 percent vs. 19.6 percent, P=0.02). Rates of preterm delivery in the progesterone group did not differ according to the week of gestation at the time of the qualifying delivery. Survival analysis showed a significant prolongation of pregnancy with 17P as compared with placebo (P=0.01). Because there was an imbalance between the progesterone and placebo groups with regard to the number of previous preterm deliveries, we performed an analysis with adjustment for this variable. The adjusted relative risk of delivery before 37 weeks of gestation in the 17P group as compared with the placebo group was 0.70 (95 percent confidence interval, 0.57 to 0.85). There were no significant differences between the two groups in the rates of hospital visits for preterm labor, use of tocolytic drugs, corticosteroid use, cesarean delivery, or chorioamnionitis.
Outcomes of Pregnancy According to Treatment Assignment.
More than half the women enrolled were black. The reduction in the rate of preterm delivery with 17P among the black women was very similar to that among nonblack women.
The effectiveness of 17P in this study suggests that only 5 to 6 women (95 percent confidence interval, 3.6 to 11.1) with a level of risk for preterm delivery similar to that among these women would need to be treated in order to prevent one preterm delivery before 37 weeks of gestation. Similarly, 12 women (95 percent confidence interval, 6.3 to 74.6) with a similar level of risk would need to be treated in order to prevent one delivery before 32 weeks of gestation.
Rates of spontaneous miscarriage between 16 weeks of gestation and 19 weeks 6 days of gestation, and rates of fetal death after 19 weeks 6 days of gestation are shown in Table 2 and Table 3. There was a small and nonsignificant increase in the rate of miscarriages and stillbirths in the progesterone group as compared with the placebo group. With one exception, all stillbirths occurred before 24 weeks of gestation.
Outcomes among the Infants
There was a significant reduction in the risk of a birth weight of less than 2500 g in the progesterone group as compared with the placebo group (relative risk, 0.66; P=0.003) and a nonsignificant reduction in the risk of a birth weight of less than 1500 g (relative risk, 0.62; P=0.08). Treatment with 17P led to significant reductions in the rates of necrotizing enterocolitis (P=0.01), need for supplemental oxygen, and intraventricular hemorrhage of any grade. However, there was no significant difference between groups in the rate of intraventricular hemorrhage of grade 3 to 4 specifically. The rates of infant death, transient tachypnea in the newborn, respiratory distress syndrome, bronchopulmonary dysplasia, need for ventilatory support, retinopathy of prematurity, and patent ductus arteriosus were slightly but not significantly lower in the progesterone group. Of the 17 neonatal deaths, 16 were due to complications of prematurity and 1 to intrapartum hypoxia subsequent to uterine rupture.
Nine of the infants were found to have congenital malformations (2.0 percent in each group). There was no consistent pattern to these defects, and none involved genital organs. One infant of a woman in the progesterone group had torsion of the testicles in utero, with subsequent infarction.
Discussion
Treatment with 17P on a weekly basis, beginning at 16 to 20 weeks of gestation and continued to delivery or 36 weeks of gestation, significantly reduced the rate of preterm delivery before 37 weeks, 35 weeks, and 32 weeks of gestation among women at high risk for preterm delivery. The rates of several complications of prematurity were correspondingly decreased among the infants of women assigned to this therapy.
The women enrolled in this study had high rates of preterm delivery, with more than 50 percent of the women who received the placebo injections delivering before 37 weeks of gestation. This high rate of preterm delivery is most likely related to the history of previous preterm deliveries. The earlier in a pregnancy a preterm delivery occurs, the greater the chance of preterm delivery in a subsequent pregnancy. In our study, the mean duration of gestation at the time of the qualifying delivery was 31 weeks, and a third of the women enrolled had had more than one previous preterm delivery. Therefore, the women in this study had particularly high risk. They were also strongly motivated, and compliance was excellent.
Preterm delivery has multiple causes. Some evidence suggests that the causes of early preterm delivery differ from those of later preterm delivery, with earlier preterm deliveries more often being related to infection. Whereas 17P would not be expected to affect an infectious process, in this study, it provided potent protection against early as well as later preterm delivery. The mechanisms of action of 17P in prolonging gestation are not entirely known. The actions of progesterone on the pregnant myometrium include relaxation of myometrial smooth muscle, blocking of the action of oxytocin, and inhibition of the formation of gap junctions. In sheep, goats, and some other mammals, a decrease in plasma progesterone and an increase in circulating estrogen precede the onset of labor. Although no such alteration in the ratio of plasma estrogen to progesterone precedes the onset of labor in primates, there is evidence that local changes in the progesterone level or the ratio of progesterone to estrogen in the placenta, decidua, or fetal membranes may be important in the initiation of labor in humans. In addition, administration of progesterone antagonists in women at term results in an increased rate of spontaneous labor.
We chose to use 17P because of reports of its effectiveness in some previous trials. Other studies showed no benefit, including a trial involving women with twin gestations and a trial in women with a low risk of preterm delivery. Most reported trials of other progesterone compounds have not demonstrated effectiveness in reducing the risk of preterm delivery. However, a recently reported trial in which progesterone suppositories were used suggested that this route of administration may be a viable alternative. The risk of preterm delivery was lower among participants in that study than among the women in our study. The entry criteria included a history of delivery before 37 weeks of gestation, cervical cerclage, or a uterine malformation. The women in the placebo group in that trial had a rate of preterm delivery of 28.5 percent as compared with 13.8 percent in the progesterone group. These results lend support to the concept of prophylactic use of progesterone to prevent preterm delivery.
Treatment with 17P also resulted in improved neonatal outcomes. Although the reduction in neonatal mortality in the progesterone group was not significant (relative risk, 0.44; P=0.08), the trial was not designed with sufficient power to address this end point adequately. There were significant reductions in the rates of necrotizing enterocolitis, any intraventricular hemorrhage, and the need for supplemental oxygen in the progesterone group.
17P appeared to be safe. There was no increase in the rate of congenital anomalies in the progesterone group. These results are consistent with surveys of the literature that have indicated an absence of teratogenic effects from the use of 17P during pregnancy.
The results of our trial should be interpreted with caution. Although 17P proved to be effective in preventing preterm delivery in our cohort of women at very high risk, it may not be effective in women with a lower risk of preterm delivery, and most preterm deliveries occur in women with no previous preterm delivery. Therefore, our results may not be generalizable to women whose risk factors for preterm delivery are different from those of the women in this trial. In addition, although 17P significantly reduced the rate of preterm delivery among the women who received it, the rate of preterm delivery in this group remained very high (36.3 percent). Thus, the identification of other causes of preterm delivery and other methods of preventing it remains a pressing need.
Happy 2nd Easter Ashley!
Technically, this is your second Easter. You were two weeks old on Easter last year, but it does not count because you were still in the NICU. We brought you a basket and a chocolate bunny, but we really could not celebrate Easter properly with you then.
This year, we did it right!!! hehe. Mommy and Daddy gave you an Easter basket filled with candy, bunnies, chicks (all for mom and dad), then goodies for you - sandbox toys, an Easter book and bubbles. Mommy also filled some Easter eggs with candy and let you play with them. I put them in the back storage compartment of your wagon, and you would take them out individually and roll them around the wagon.
Grandma and Grandpa Bledsoe stopped by and dropped off an Easter gift for you too. Then, Mommy, Daddy and you dressed up and we went to Grandma and Grandpa Szilagy's for dinner. You were in a really cute dress and played the part well. You got even more goodies at Grandma and Grandpa's house. You also ate ham for the first time and devoured it!!! You could not get enough. It was so cute!!!
Happy Easter punkin!!!

First Birthday Party!!!!1
We had Ashley's first birthday party yesterday. Her actual birthday is not until Tuesday, but we wanted to celebrate her birthday early. Plus, it did not hurt that the party was on Easter weekend, so more people could attend. In all, we had 18 people there - which is a great turnout, considering that I have a small family and Bryan's extended family lives out-of-state. Our family tradition of bad weather when hosting special events continued. The night before the party, Michigan got hit with a snowstorm and we got about 6 inches of snow. Proof that any type of weather can occur here!
Anyway, we began the party by serving chips and Mexicali dip, and crackers and spinach dip. Both are family favorites. Then, we served a buffet-style lunch of ham and turkey sandwiches, macaroni salad and fruit salad. Everyone seemed stuffed - even the birthday girl. She ate turkey, turkey and more turkey. She also charmed everyone, as usual. She was flirting with her Uncle Dennis and smiling at everyone like usual.
After lunch, we opened presents. I was afraid that Ashley would be running out of juice because this was around naptime. Sure enough, she did not want anything to do with opening her presents. At Christmas, she would pull the wrapping paper off her gifts, but yesterday, she refused. She got a great haul of presents - lots of clothes, toys and money. It pays to be the first grandchild.
Ashley continued to get fussy, but we did not want to put her down just yet because we wanted the ever important first cake experience. We bought her a two tiered yellow princess cake, then also bought her an individual smash cake that read "Happy 1st Ashley." Unfortunately, we do not have good pictures of the smash cake (someone else was taking the pictures). I am hoping that one of the grandparents has a good picture we can copy. We put the "1" candle in the smash cake and sang "Happy Birthday" to Ashley. I blew out the candle for her and placed the cake in front of Ashley. At first, she refused to touch the cake. So, I put some icing on my fingers and let her taste it. Well - that was all it took. She LOVED the icing and dug right in! By the time she was done, there was frosting in her hair, on her face, on her arms, on her chest and on her legs. Thank goodness we stripped her to her diaper. She clearly enjoyed herself!!
Happy Birthday Princess!!! You have come an awful long way in a year. Mommy and Daddy love you so much!

Waving to the world and pulling up
Ashley has been waving for a while. At first, it seemed like a random movement. She would move her hands up and down, but never really with a purpose. That all changed yesterday. She started a waving jones yesterday. When she saw her reflection, she waved. When she saw pictures of herself, she waved. When I went into the other room, she waved. Can I just say that my daughter is the most adorable baby in the world???
She also began pulling up with a lot more consistency yesterday. Before, she was able to pull up on Bryan or me, or, sometimes, on her Sing-Along-Stage. Yesterday, she pulled up on me a few times, her stage, her Leapfrog table and her baby grand piano. She had a look of awe, satisfaction and bewilderment on her face. I love watching the wheels turning in her head! She has finally realized that she can pull up to do whatever she pleases. I am sure there is no stopping her now.
One last piece of news - Ashley ate cottage cheese this morning. She really like it! Then again, what doesn't my daughter like??

Eating More "Adult" Foods
Ashley ate three new adult foods today. First, she ate Honey Nut Cheerios and according to Bryan, really liked them. Surprise, surprise. She will eat just about anything. The second new food she ate today was macaroni and cheese. She really seemed to enjoy it and kept opening her mouth wide for Bryan to shovel more in there. Then, a little later in the day, we tried a small amount of peanut butter. Since no one on either side of the family has a peanut allergy, we let her try some. Ashley opened her mouth wide, sucked the peanut butter off the adult spoon and proceeded to swallow what was in her mouth, then open her mouth for more. She liked the PB so much, that I put another spoonful on a plate for her. We were not surprised she liked the PB because her Daddy absolutely loves the stuff. In fact, he takes at least one PB sandwich to work in his lunch every day.
Then, at dinner tonight, Ashley ate quite a bit of chicken from our quesadillas. I think there will come a time, in the not so distant future, when Ashley will be off baby food completely. She only has two front teeth, but she does a great job of gumming and chewing her food. It's hard to believe our baby is growing up.

I admit it, I'm really bad at this!
Apparently, it has been three months since my last post. Shame, shame. I told you that I am not very good about this.
Ashley continues to do well. She will be a year old in less than two weeks, which just blows our mind. We cannot believe it. Where has the time gone? She had a pediatric ophthalmology appointment yesterday to monitor her retinopathy of prematurity (ROP for short). Her last appointment was in May. She still does not have ROP, which is an abnormal growth of blood vessels in the eye. Apparently, during the last trimester of a fetus' life, their eyes develop rapidly and finish developing. Well, because Ashley was born at 28 weeks, she missed out on her entire 3rd trimester. So, there was a very, very good chance there would be some ROP. Check this off our list.
Unfortunately, we did not receive totally perfect news. Ashley has slight nearsightedness and very, very mild astigmatism. Nearsightedness, in particular, is also a complication of prematurity. So far, she does not need medication or glasses, but I am sure glasses will be in her future.
As for baby #2, I am 14w1d today. This pregnancy seems to be flying by. I am still sick, especially in the morning, but today I did experience dizziness and lightheadedness while at work. I felt so bad, that I almost went home early. Luckily, the feeling passed, but I am so ready to be done with the yuckiness of the first trimester. I SHOULD be done, I'm in the second trimester already.
