Just a period question?

If you're on birth control, used a condom during , AND are experiencing bleeding, I seriously doubt that you are pregnant. It is called breakthrough bleeding and should not last too long- certainly not as long as a normal period. I guess you should check with a pregnancy test because there is always that slight possibility that you are, and to be honest, you probably won't stop worrying until you get a true answer. Don't stop your birth control, just continue taking it like you should be unless you experience other side effects that could indicate that its not working, in which case you should talk to your doctor.
