Great report, Mo! It sounds like your OB really knows what he's doing. Amazing that you heard the hb on Doppler!
Anxiously: I had my NT scan at 12 weeks. We were told that gives 75% of the probability for Trisomies 13, 18, and 21. When we were there, the dr told us about a blood test named Verifi (verinata.com) that gives 95% probabilities. But they only give that of the NT test shows elevated risk, because it's probably not covered be insurance and costs $200. We asked to do it anyway, and said we'd gladly pay the $200.
I think other companies offer a similar test.
Brandy: is the Harmony test you took the same thing? Btw, they told me 2 weeks also, but got back to me in only one week.
