Yeah, a woman's period is like a wet dream...it happens when it happens and you can't make it come consciously.
If she is sexually active it's vital she see a gynocologist at least once a year to ensure there are no infections or other bad things going unnoticed. She might need to have two visits to get her prescription for birth control because the doctor might want to wait for the test results after the examinations.
Birth control is a good thing for many people because it evens out the hormones and generally makes you feel more stable. I loved taking the Pill for those reasons--my headaches, cramps, bleeding, and general crankiness were all much improved, plus I always knew when to wear a pad!
If I may indulge myself in one brief editorial statement, why are you continuing to have sex with a girl who is so irresponsible that she won't take care of her own health? Keep in mind it also affects YOU if she gets pregnant or sick! Tell her she can't have any more of your hot ass until she gets HER hot ass into the doctor's office
