Hello, I'm 22, 1,63 meters height and around 50 kg weight, sexually active, no prior health problems, always use condoms. My menstrual cycle is a bit odd, it lasts around 35 days with a period of about 7 days (counting the prolonged brown discharge). This time, about mid-cycle, i guess around ovulating i started having a brown discharge with streaks of blood, normal pain in the lower abdomen, as i sometimes have around my period; it was a small quantity at first, but then it increased, though it was not continuous, then it stopped for a few days in which i had sexual contacts with my steady partner, now it started again, with increased quantity during bowel movements. No other symptoms. I have no idea what is wrong, but it doesn't seem like a disease. What do you think?
