you honestly do not have a good chance of getting pregnant the day before your period, only around ovulation time and not too many women ovulate the day berfore theire period.
My friend and 2 older sisters both got pregnant on the pill. It's not fool proof. However a day before her period is highly unlikely. Best of luck, either way you want this to turn out!
I agree...unless you missed a few pills and you were off on when your period was due, you're probably not pregnant.
there is always a chance anytime you have unprotected sex. but, the chances are very, very slim.
i think if u r on pill, there are no chances of pregnancy,,if u have skipped thme on the day of ovulation,,,or if u thought u might be ovulating on 13 day,,and skipped any pill later,,,there are chances of pregnancy,,if u ovulated later in that cycle!
