Your age is factored into the ratio so that may be why some of your results have come back looking "normal" and yet your number is so low...the same thing happened to me too. It's important to remember the NT screen is just a SCREENING test only and doesn't necessarily mean anything in real terms.

We opted to have the CVS but it's really important before you have the procedure that you have thought about through the implications. What do you plan to do if this baby does indeed have trisomy 21...or another form of trisomy? It's a good idea to ask to see the genetic counsellor at the place you are having the CVS - they will help you get across the information and understand what it might mean.

Our CVS results came back normal and I now have a healthy nearly 2 yo. A friend's best friend had a NT result of 1in2 and she also ended up having a normal healthy bubba. It's a lot of uncertainty right now but you will get through this ok .
