hi everyone, okay so my girlfriend and i had sex a couple of times this months and yes i did use a condom. She got her period on time and that was the 24th. She got her period on the 24th last month and the month before.

I am very sure that it was not implantation bleeding judging by how she described it to me and what she said was "it's so heavy and red, it leaked through my tampon and my pad" I know it's not implantation bleeding because it said to be very light and only lasts a couple of days and she was on her period for four days. 

What i'm worried about is that she says she still has cramps and she got off her period two days ago. I've looked it up on the net and all it said were post period cramps and some said pregnancy. Can anyone please help me on this, I really am scared.  Thanks
