So I had my blood drawn, at 10 weeks for ds, and they called me, and I ask was is serious, and the lady said no and I was like ok, and she told me the ds came back positive and only 1 out of 800 children are born with it and next week I'll be 12 weeks 5days and they want to do a ultra sound. I looked up on line and it said the test done at 10 weeks your more likely to get a false positive, this will be my 3ed child and I just don't know what to think.
