When did you conceive if your due date is April 24?

August When you are pregnant & want to figure out the due date you add seven days to your last menstrual period and count forward nine months. so you would reverse that. So you got pregnant around July 17. I'm studying to be a medical assistant and we learned that. FORTY WEEKS PRIOR TO THE DUE DATE. WHICH I BELIEVE WOULD PUT YOU SOMEWHERE AROUND THE LATER PART OF JULY.
ANSWER - the due date is actually calculated from the first day of your menstrual period. If your due date is April 24th, then your first day of your menstrual period was July 17th. The date of conception is calculated to be two weeks from that date, which would be August 1st or so.
