So I'm pregnant with my 3rd child at my 13 week scan they found extra fluid behind the neck, I did a blood test screening and it's come back at a 1 in 2500 chance. They booked me in for a scan at 16 weeks which I went to the other day and found more problems, the baby has bright bowel and also a thigh bone is growing a week behind they said this also is a sign of Down syndrome but could also be minor they offered me the amnio test which I accepted cause I'm not sure I can go the full length without knowing, I'm booked in for Friday but now it's getting closer I'm starting to worry more about having it. Would anyone be able to tell me there experiences with this and also if they had any of the signs above? Thanks in advance
