With my 1st 3 pregnancies NT was not routinely done so i did not have them and all my boys were fine.
With my 2nd husband and our 1st baby i decided to have it done as i wanted to know everything we were in for and to be prepared for any problems bub might have we said we would never terminate a down syndrome baby but what people dont know it the NT also detects other genetic problems ect our risk came back at 1 in 2 for a chromosonal problem we wanted to know what the baby had so we had a cvs it came back all clear so we had an amnio it came back all clear but all the u/s picked up multiple abnormalities and by the time we got to 19 and a half weeks we found out our daughter was not viable with life and could die in utero any time or would die at birth so the decision that i said i would never terminate changed as it was the kindest thing to do for our baby i dont think anyone can really make that decision until they are faced with the reality of being pregnant with a serverly abnormal baby and what is the best and safest option for mother and baby.
I am currently almost 13 weeks pregnant and have had the NT and another cvs because i need to know and if faced with the same heartbreaking news i would not continue the pregnancy to just watch this baby suffer a horrible death once born.
The NT is just a test for markers that could indicate a bub with problems but i can tell you it opened my eyes and i will never take a pregnancy forgranted ever again.
