I had my nuchal translucency ultrasound today. I was told the thickness is borderline (2.8 cm). They consider 2.5 cm as cut off point for normal. They draw my blood to do an extensive chromosomal abnormality test. Including the trisomies and microdeletions. OK, no need to mention how much both me and my husband are down and freaked out. Even if the blood work results are normal, there is still heart abnormalities that need to be ruled out and that happens at 18 weeks ultrasound. Does anyone have same experience? How many of you ended up having a healthy baby?
