I'm 31w4d I conceived on 2/14/12 my due date is 11/7/12. I knew I was pregnant on 2/25 my period was due on 2/28/12
its possible to feel pregnant before you actually are some people just instinctivly know, after all pregnancy is calculated 2wks before you're actually pregnant anyway. Also usually if you had an early ultrasound that would give you the most accurate date
I'm due anywhere from Oct 29th till nov 1st. Doctor's cant make up mind. I also tested before my missed period and was positive. I honestly am not worried the baby will come when she wants. I wouldn't worry either If I were you.
