Now which is the official dating scan, the 12 week one or the 20th week one?
My dr got so angry and upset that I missed my 12th week scan and she said without that my sure date cannot be accurate made (sure dates are an estimation no matter what they are isn't it?) But the thing is with my last pregnancy my dr who I have birth to changed my due date by a week before depending on the 20th week ultrasound, then why on earth does this women make life miserable for me. (I am high risk after 3 losses) but I don't think so a 12 week scan can do anything on those regards.
12 or 20 which one does your dr prefer?
