NT scan

Courtney

So I usually opt out of the NT scan, but since I’m having twins I wanted to make sure that babies were growing properly. From the scan the Dr. said she is very concerned with the Measurement or fluid behind baby A’s neck (3.0). However after reading articles online it seems to say that most babies that measure 2.5-3.5 are fine. Does this seem right? Did anyone have an experience like this? My test was done at 12weeks 5days.
