Hi I'm 21 and have polyasytic ovaries and when I'm on my period and I have a BM or when I'm just gassy it hurts extremely bad in my colon like a knife is being twisted around. My endometrium increases to 8mm thick when I'm menstrating. Also it is very difficult to put a tampon in I have to push under and around a wall. If u have any information it would be greatly appreciated. Thanks
