Yes, I do. It is awful first of all. I had severe symptoms about 5 years ago. I was always a person with severe cramps, clots etc. Well, I got my period, and the second day which is the heaviest, my period stopped right in the middle of all of that and the pain, fever, nausea, was so severe. Then the next day it all eased up, skip to the next month and it all happened again, worse than ever. When to gyno, and had a pelvic in the middle of my period(ugh!!) and he said I had severe endometriosis just by the feel of my insides. They were all knotted up and ropey. So I started to take bcp for a year straight. NO periods for that time but I would have days on end of this brown/thick discharge that was horrendous. After a year I went off of the pill, and my periods were ok. Dr said it put me in a remission but it might come back, might not, so far so good. Its been five years now and I still have horrid cramping, clots, heavy flow for a few days and also a typical sign that I hear is common is a lot of cramping throughout the month in pelvic area. Hope this helps you out a little.
