I have my 12 week scan on Wednesday and am tying myself in knots worrying about whether to nuchal test & bloods or not. DC1 has SN, didnt do nuchal test back then but my bloods were clear. Turns out condition couldn't have been detected till 20wk scan where it was noticed. With dc2 we didn't test and scanner refused to measure nuchal translucency as wasn't opting for bloods.
This time round I am older and not sure what to do. How accurate are the tests? Friend of a friend had very low odds, like 1:2000 and her baby had Patau syndrome and is sadly no longer with us which is one that they look for. So can you believe results even if risk is low?
So confused and worried, hope someone can help
