Yes, sorry, 3.2mm and at my 13 week scan was 2mm.
I'm also concerned why they felt the need to measure my babies, this has never happened in my other pregnancies (I'm in the UK) I don't know if it's because they were having problems getting the right measurements of the babies heart because of how he was lying?? But I didn't think they measured it in an anomaly scan, will be asking my consultant this when I next see him, will let you know what I am told.... I hate the worrying!
Proud mummy of 2 wonderful boys and now a 3rd one one the way
