I've just had my ultrasound scan at 13 weeks and everything was going fine, the baby was moving and the Sonographer was pointing out all the different body parts to us and then suddenly the Sonographer advised us that the fluid behind the baby's neck is 8 mm which is much higher than normal (up to about 3.5 mm is considered normal) and this means there is an increased risk of having a baby with downs syndrome, chromosomal abnormalities or major congenital heart problems :(. We were totally shocked and devastated as I really hoped everything was going to be okay this time as I had 2 scans at 7 weeks and 10 weeks and everything seemed fine. I am now waiting for the results from the blood tests to get my overall risk of having a baby with one of these conditions but as I'm sure you can imagine waiting is a nightmare!. Has anyone else had a high measurement? If so would you mind sharing the outcome?. I was really hoping to be able to relax after this scan as I had a miscarriage last year at 11 weeks (blighted ovum) and now I am even more worried than I was before, I just want my little baby to be ok :(.
