I’m actually relieved to know that I’m not the only one! It doesn’t happen every time, but usually when I’m really pushing myself. I had the theory that it might b endometriosis, but I’m afraid of getting the tests to try to get an answer about that. I have some crazy hormones/cycles–ever since puberty. Maybe cysts? I also notice a correlation with my right iliopsoas (pelvic floor muscle that attaches to the low back and femur and assists with leg flexion: I.e. running) starting to burn/cramp, seeming to set off the uterus. I’ll have to google it and see what some blogs and forums say…thank you for the post, and good luck finding answers!
