I'm asking this for a friend. She's 15, and is having problems with her period. 2 years ago she met a guy and they started having sex almost weekly for 1-2 years, not using any kind of birth control, and not pulling out during ejaculation. She hasn't had any signs of pregnancy since that point. Since January of last month, her periods have stopped, until today. She is going to the hospital for blood tests soon, but, they don't even know that she's had sex like that before. They have no knowledge of this, I told her that she absolutely needs to tell them that information. Her period started up about 5 minutes ago, I can tell she doesn't like talking about this, but I managed to hopefully get enough info to help her out. Any responses are appreciated.
