I do agree that the chances right now are there, though slim since she was on her period. Anytime you have unprotected sex you risk the chance of pregnancy. Since you had unprotected sex, there is a chance but if she was toward the end of her period, chances are the egg had already been released.

Now, when on birth control, a girl doesn't ovulate. So, there really isn't anything to worry about. It's not even a real period, but what's called breakthrough bleeding. Just wait it out two weeks and then suggest she takes a pregnancy test.
