i had unprotected sex on friday 10th september...saturday (less than 24 hours) i took the morning after pill (postinor 2) and 12 hours later i took the second pill on sunday... i had unprotected sex yesterday and he didn't ejaculate into me...but on top of me... is it possible that leaking or precum will make me pregnant? should i take another morning after pill? also, how soon can i take a pregnancy test just to make sure?
