I am 24 years old, I have always had regular periods, my menstrual cycle is usually about 30 days. this month instead of getting my period, I got a reddish brown discharge on the day my period's due. I felt cramps 3days prior getting that kind of discharge. But now I am having a light brown discharge and no blood at all. I have never had sex before, however my boyfriend and I made out 5 days ago.. ( no ejaculation near my vagina and no penetration just slight forttage). what are the chances I am pregnant? And if I am not what could this possibly mean? P.s: I took 2 pregnancy tests and both came out negatively. thank you,
