As pregnancies are not all exactly the same length you cannot tell from the date you give birth. It would be difficult to tell exactly when you conceived as you have about 7 fertile days a month, but you can narrow it down by seeing which days you had sex in your fertile period.

I found out I was pregnant october 29th and I'm due june 28th when did I get pregnant?
