Hi, I had sex with my boyfriend about 3 weeks ago. During this, I started bleeding. At the time, I just thought he went a little deeper than normal and shrugged it off. I got my period 2 days later (on time). It lasted the normal 7 days. Well two weeks later (2 days ago) i started bleeding agaib, nothing to heavy, but definitely noticable. I am still bleeding now. Should I be worried?
