Quoting pretty 'n' pink:" Okay so as some of you know I just had an abortion and my bf had been confusing the hell out of me. well ... [snip!] ... paranoid. I mean if im still bleeding them my body is still cleaning itself out right? has this ever happened to anyone else?"
of course it's possible. Anytime you have sex you could get pregnant. Anytime you have sex without contraception or before contraception is effective.. you especially could be pregnant.
if you're still bleeding... lower chances... but still possible.
