Ok so I went for my second anomaly scan last week (22 weeks) and noticed that in the notes box she marked the NT at being 4mm I read that any measurement taken after I think it was 16 weeks means nothing but I have seen some measurements on here that say theirs was below 2mm at around 13 weeks. The sonograther mentioned downs to me a couple of times during the scan, once while doing it asking if I had the triple test etc and then at the end said that this scan wasn't to confirm downs. I hadn't mentioned it once. It started bothering me and then seeing the measurements that some had at 13 weeks wondering if I should be concerned at all? I know I am 22 weeks but with the measurement being 4mm and the sonographer just mentioning downs out of the blue I feel a bit concerned now.
