I just found out I have Polycystic ovary syndrome. I have not started my birth control treatment yet. But I was lightly bleeding for two days and still did not start. My period heavy. Then day-three days later after the light bleeding. I noticed this dark thick brown discharge. I usually dont have discharges. I don't use protection. And I still have not started my period yet. I have slight pains but I have high pain tolerance. What is this discharge about? Should I see my doctor?
