Does anyone else suffer from MUCH worse symptoms during their menstrual cycle? I actually have to do my Lamaze breathing exercises when I have a BM during my first couple of days. For years, my Dr. was under the assumption that I had endometriosis, but just last year I was diagnosed with diverticulosis (which turned into diverticulitis 4 separate times) that was caused by my IBS. I guess I'm still wondering if hormones during that time of the month is aggravating it.
