i was going with the second one but go with the first one is more accurate... i had same prob and she was born 2days before the first date they gave me

my doc is going off my original one from my last period but the hospital is going off the 12 week scan.. they are only 3 days apart but im with my doc on this one! haha

Thanks girls :) that's what I've been doing

yeah they usually go from 12 week scan

I got told they usually go off the second scan which is the one around the 12 weeks mark.
