How To Find Out Date And Day I Got Pregnant If My Due Date Is May 9,2009?

Pregnancy is calculated from the first day of last menstrual periods. Date of conception is always approximate because ovulation takes place at mid of the cycle but some ladies can ovulate earlier and some later. Conception date is calculated by adding 2 weeks in your first day of last menstrual periods or by subtracting 38 weeks from your due date. If your due date is 9^th May, 2009 then your possible date of conception is 16^th August, 2008.

In all honesty you can't... Sperm can live in the fallopian tube for 5 days after sex and the due date is estimated nine months after the last period and they usually add a week.
