Hi Jessy and welcome to BB.

Firstly, a 1:230 chance of Down's is a 229:230 chance of "normal", so it's up to you how you look at the statistics.

Second, I believe the fold should be under 4mm at the scan, which it was for your baby, so that's something else that's going OK. My baby was a wiggler too and it took the sonographer a few tries to get a good scan of the nuchal fold (?1.3mm, but I'll double-check), although I wasn't banged about! I'm going to check my notes later and post back, but I think the heart rate looks similar to my baby's too. Hmm, not sure if they could measure the heart rate, the baby was that wiggly, but I'll post any details I have!

Where abouts are you in the world? Just I can't read your blood results and normally I can read results! There are other scan tests that can be done at the 20w scan, like looking at the heart development, but I would talk about the slight chance of a Down's child with your DH, just in case. I know I would not have liked to have that conversation with my DH, but we were lucky with the results so avoided that. Still, it's something to think about.

Feb babies are fab anyway, so I'm sure you'll have a great baby no matter what!
