I want to find the date that I conceived with my due date, because I don't remember my last menstrual period? my due date is on October 25, 2008 if that helps I would really would want to know.. thanks!

Rough guide would be to count back 3 months from your last period and add a week... (given a due date of Oct. 25, your period may have about Jan. 18)... so this would put you at early Feb. as a conception date. It is only a rough guide however, and you could have gotten pregnant a bit before that time or after. Unless you knew your body extremely well or had medical assistance, most women won't know the exact date of conception.
