My boyfriend and I had sex about 4 times in the past month, usually a week or more apart. The first time, I did not bleed. But after this past fourth time, I have a very light pinkish brown discharge coming out, and when I wipe after urinating, there is a little bit blood. I'm kind of worried, and I was wondering if this is normal? It's been 1 day since we last had sex. Please reply!
