I think I may have endometriosis, but I don't know. I am 22. My mother and my sister both don't have it, so I wouldn't think that I would, and I have a 4 year old. Anyway, it's been over a year now that I have been having problems. My period always hurts but I'm sure everyones does. The pain is not unbearable. I started to have pain during and after sex, and it seems as if I have an orgasm, I hurt after that too.
