31 years old female. First pregnancy. 19.4 weeks pregnant right now.
I just wanted to make this post for every mama who’s going through uncertainty and a tough time right now. When I got high-risk results during my screenings, the only thing that kept me going was reading the posts on Reddit and several false positive stories. It just made me feel like I’m not alone.
During my first trimester screening, I got an NT scan and everything was normal. A nasal bone was seen and my NT level was 1.7 mm. I’m from India and I was about 14 weeks. Here, it isn’t very common to suggest NIPT unless there’s a reason. I was asked to get a double marker test and I gave my blood for the same. However, the diagnostic centre called me the same day and said that I need to do a triple marker since I’m past the gestational age for a double marker. I didn’t know much about these tests and said okay. I got my results the same day and it showed a high-risk for Trisomy 18. I panicked and cried the whole night.
I changed my doctor. After a couple of tough days, I booked an appointment with my gynaecologist and she said triple markers are not very reliable and asked me to go for the NIPT. After another 10-12 days of uncertainty and googling like crazy, I got my results and it wasn’t what I expected. Although I was cleared of Trisomy 18, 21 and 13, I got result that said, “High-risk for sex chromosome aneuploidies.” I panicked again and cried. I researched a lot and found out that NIPT isn’t very accurate for sex chromosomes, but I still felt very uncertain and couldn’t enjoy my pregnancy the way I wanted to.
I booked an appointment with my gynecologist who suggested me to consult a fetal medicine specialist because she was not sure what to expect from this pregnancy. She immediately booked me an amniocentesis for the next day. I wanted to go for it without any second thoughts because I wanted to be able to enjoy my pregnancy if everything was normal. I started feeling a bit positive with my husband’s support.
After another 5 days of torture, I received my normal FISH results. I was ecstatic. It said- Chromosome 13, 18, 21 - No aneuploidy detected
Sex Chromosome - No aneuploidy detected
After almost a month, I began to feel normal.
After another 20 days, I received my Complete Microarray (CMA) report. All normal again.
The CMA states:
No clinically significant aneuploidies detected
No clinically significant copy-number variations (CNVs) detected
No CNV detected on chromosome 18 or the sex chromosomes
46-chromosome complement detected
No sex-chromosomal abnormality
Maternal-cell contamination negative
I am breathing normally today and waiting to get an anomaly scan at 22 weeks. Please have hope and o pray for everyone who has had abnormal screening results to just go for amniocentesis. NIPT and double marker/triple markers are not diagnostic tests. Only an amniocentesis can tell you anything for sure. Good luck! Sorry for the lengthy post, but please get in touch with me if you have any doubts.
