I am 34, had 4 children without complications, history of rupturing cysts and painful period since I had my last children (twins 11 yrs agao) had a tubual ligation when I had the twins. I had a D & C, laporoscopy and hysteroscopy about 5 mnths ago, for polyps of the endometrium and cysts on my ovaries. - all tests came back normal, they have recently (just over a mnth and a half) on the pill to see if my pain would ease and to stop ovulation I have been informed to take it for 3 mnths and then have a cycle, I have been very vigilant with the pill - if not borderline obsessive with it.. It has been helping and there has been no pain since. The past 3 days however I have started to bleed old blood and the occasional frank red blood. should I continue with the pill, should I be concerned that since I have had that procedure there could be old blood - high chance of infection happening in my uterus. ?
