I lost my virginity of the first day of my period last month. I am about a week late for my period and i masterbate a lot. In the middle of my cycle, I did it almost every day for a week and noticed that I had dark brown discharge afterwards. Towards the end of the week the strange discharge lightened in color I saw the tiniest ounce of red blood and then it stopped. About two weeks later I began to do again and have noticed fresh blood in discharge. Is this normal?
