My best friend's (then) 14 year old daughter had an ovarian cyst that ruptured and her symptoms were almost exactly what you've described. Apparently they will continue to come back so the ER doc suggested putting her on birth control pills as for whatever reason the hormones in them help to control the formation of ovarian cysts. But I would most certainly keep going back, with someone you trust, and be a real "bitch" if you have to until you get an answer that makes sense to you. Doctors are only human, after all and they can make mistakes, too.
