i was wondering back in 1993 is had endrometrosis in my bowel tract and had surgery to remove it. my gyno. told me there wasn't any in my female organs and only in my bowels. my question is since i had the surgery to remove it will it come back? the reason why i am asking is i have been having spotting about a week to 10 days before my period and its brown and sometimes pink in color just enough to wear a panty liner also i have lower stomach pains and cramps alot and very hard periods that last 7 days. just trying to figure out what is going on. thank you all so much.
