A member asked:

My dating scan measured me 12 weeks and 6 days when i counted this back it took me 2 days before i had a bleeding. did i conceive before the bleeding?

A doctor has provided 1 answer

Probably not: By convention we date a pregnancy from the start of the last menstrual period and not from ovulation. It has only been relatively recently that we could determine the time of ovulation and thus the time of conception.
