Hey!
My parent's don't know that I am having sex! And whne I have rough sex only I bleed a little bit but only for like 10 seconds and that is it?

What is it?:confused:

It depends on how rough the sex was. It could be something a little more serious. You could have a polyp on your cervix, or endemetriosis.
Have you been seen by a gynecologist? If you are sexualy active, you need to see one. I assume you are practicing safe sex. If not, you are opening yoursef up to a large variety of invaders. Some of which can cause you to loose your fertility.
It is a nasty mean world out there, if you don't take it upon yourself to protect yourself, certainly no one else would do it for you.
