Pelvic pain

I’ve always had heavy irregular periods growing up but they were never this bad. It’s gotten to the point that I am having pain & spotting between periods & skipping up to 2 or 3 periods at a time, & when I do get them I’m in so much pain that I’ve thrown up, I could barely even stand up straight because it hurts & it’s so heavy from not getting it consistently. I’ve had ultrasounds, Pap tests & exams & everything is coming back normal. The only thing I’ve gotten from my dr is that it is more than likely just a hormonal imbalance & the only way to fix it is to go on birth control, which I’ve told her does not agree with me. I tried it for years when I was in high school. Different kinds & all it did was make me feel physically ill & affect my mood negatively. I’m just curious if there are other people out there who are going through something similar that might have some different alternatives?
