Patient's question:
Patient Age: 16I have not had my period yet. Why did I bleed after having sex with my boyfriend?
Doctor's answer:
There are two situations: one is that you have hymen occlusion, meaning the hymen has no opening and menstruation cannot flow out. However, you experience regular abdominal pain each month. The other is a developmental issue, meaning you do not ovulate each month, so you have your period. In either case, it does not affect bleeding after first sexual intercourse. The hymen is just a thin membrane at the opening of the vagina. It is unrelated to your development. However, if you do not ovulate, you will not get pregnant.
