The blood test they did for spina bfida and other chromosomal abnormalities such as Down syndrome, trisomy 13 & trisomy 18 came back today and every thing came back as low risk. But the 20 week growth sonogram they did today came back as thicker than normal on the back of the babies neck which is a sign of Down syndrome. So they took more blood and did some other test that's 98% accurate in detecting Down syndrome and I get the results in a few weeks. Anyone have low risk on the screening test and had the babies neck thicker than normal and didn't have Down syndrome? I'd love this baby no matter what but I'm scared 😔
