They count the first day of your last period as the day you got pregnant. You didn't actually get pregnant until at least two weeks later, but since ovulation, conception, and implantation can not be pinpointed exactly they use the first day of your last period. Your first ultrasound they'll measure the baby and it may change the due date by a couple days.

I just needed reassurance that this wasn't pregnancy from before my period.  Lady who did my ultrasound told me no but there doubt in my mind for reason...maybe guilt.  But I won't stress anymore and leave it in gods hands.

You would have conceived, theoretically, about 14 days after the first day of your last period.
