When i found out i was pregnant i knew exactly when i last had af so my due date was the 22nd of may.
At my first scan according to my dates i was 8 wks and the scan showed exactly the same.
I had my NT scan today and i was 11wks+5days by my dates but she changed my dates to be 12wks+1day.
So does this mean that i ovulated earlier then i thought( which is disspapointing as we tried the whole shettles method to concieve a girl) and i know that its no guarntee but thought it was worth a try.
Or could this also mean that the baby is a bit bigger then normal?

Hope this makes sense
thanks for you help Nikki
