Hi, I don't know if the right person will get this message, but my computer wasn't letting me reply to the message directly. There was a person with irregular periods and pain and it sounds exactly like what I went through and I was diagnosed with Adnomiosis (a version of Endometriosis) You should have a internal ultrasound. They first told me it was probably a bladder infection, which it wasn't, and I told them I wanted an internal ultrasound. I had heavy, heavy periods, pelvic pain, pain around tail bone, frequent urination, sometimes pain in upper legs. Well, I hope the right person gets this message.
