ovulation

Ok so I haven't had sex since march . And I have gotten all my periods since then . and every month I get dark brown discharge. However this month it was more then usual. Last month I had a heavy flow. I've been having discharge for the past two days now. It's suppose to be clear by now. I hope I'm not pregnant. I haven't had sex. Although I did do things.
