Hi i am pregnant in my due date is february 28 2015 in just want to find out when did i get pregnant?

Pregnancy calculator: Here is a helpful calculator that you can use to estimate. http://americanpregnancy.org/duringpregnancy/pregcalc.html

Early June: Your due date is 40 weeks after the date of your last period. For a February 28, 2015 due date, the date of your last period should have been very close to May 24, 2014. Conception should have taken place approximately June 7, 2014. Hope you have an uneventful and healthy pregnancy! Good luck!
