August 13 was the first day of my period. I had intercourse last August 21. He pulled out of mine just before the semen went out but we didn't use any condom.. 3 days after I had a brownish discharge. It went on until this day, August 30. Last August 28, the discharge was more plenty and blacker. Today,August 30, I have more discharge than ever, and it it blackish brown. What does this mean? Am I pregnant or am I sick or something?
