[ For the passed couple of days I have had a brownish discharge and occasionally a small amount of blood that was not mixed with my discharge. The blood might appear today only once and probably the next 2 days. I had recently had sex 13 days ago, my boyfriend did not at all after which my discharge was clear and thin then it became brownish with occasional blood. So what could be my problem and is there a chance that I might be pregnant?:confused:
