Okay mommies. when I was 10 weeks they found fluid behind the babies neck. it was bear ly over the normal range. my blood work came back negative for down syndrome and mine and my husbands chromosome analysis came back normal that we don't carry anything. there is still fluid behind the babies neck though I'm 15 weeks today and go see a specialist in 3 weeks. Any ideas of what it may be since we don't carry any abnormalities?
