Today I had sex with my boyfriend, & during sex he stopped and there was a brown discharge that was in clumps. It had no smell but the color was a dark brown, and I was bleeding. I got home & there was blood in my panties, and more brown discharge. My period came late this month, so I was thinking it might just be old blood, but the opening of my vagina is a brown sort of color now. It looks like some type of infection
