Hi I m getting what I thought is my period but it s like a very dark brown/ black, very stringy (I touched it and it pulled like a string) discharge mixed with red blood & clots. I see it on my tampon but if I wear a pad, nothing comes out. I m really concerned. I ve had this previous in my last menstrual cycle, I had a normal period, had sex and the week after it happened for a few days ( I assumed it was just old blood making its way out) Now it happened again but without the normal period beforehand. I was taking Cerzette mini pill which I just stopped taking a week ago. I m not experiencing any pains or cramps. Should contact my doctor?
