Hi, I am an unmarried girl and getting treated for adult acne caused because of harmonal disbalance. I generaly gets cramps before my periods but i did nt get any cramp this time and after 25 days of my periods had blackish red clots kinda bleeding. The flow was neither too heavy nor too frequent. But it was there for 1 week. After that for one week everything was okay. I thought it must be my period without pain. But again after one week i am facing the same issue. Same blacking type of bleeding. Could the medicins be a reason for this irregular bleeding??. Pls suggest. Thanks
