I have endometriosis, I know this. but, for the last six months or so, I have had consistenlty two periods a month. exactly two weeks in between. recently, I just finished my period and went in for an exam and the next day I started my period again. it started as a trickle and then became like a normal period after that. I have noticed in the past sometimes intercourse could also start my period. does this mean I have scar tissue in the vaginal region? or should I worry about cancer. My mother had uterine cancer. and I am a smoker. all the women I know who have had such irregular bleeding has had cancer. I have had my paps done regularly.
