NT measurement? Update at bottom of pg1*

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.

 

I asked my MW today about this and even she didn't know so she called the sonographer up while I was there and we sat and waited for a call back. Took forever so she called again and scan woman had just taken another lady into be scanned so she said she'd chase it up and ring me. Got a call back this afternoon to say that she had done some digging and as long as it is under 10mm at my stage its OK.
PHEWWW I still know its poss to still have issues with anything *touches wood I don't* but at least that's a weight off my mind!
