Okay, first off.. My period was 2 days late. I had ONE day of blood (mixed with a brownish pink discharge and that was my THIRD day) in my FOUR day period(usually a full 6 or 7 days ).. & The First, Second & Forth day were brownish pink discharge. I only ever saw little spots of blood on my tampon that one day but only a couple times.. My periods are VERY regular and VERY heavy so I'm wondering should i test? This was just this weekend that just passed (7th - 10th ) . I am sexually active ( Last time before this happened was on the 2nd, and before that was the 24th & my last period was August 2nd-9th) , I am on birth control , but missed a pill that last month ( I had sex with my fiancee & he did cum inside me). Also, I have been on this birth control for about 8 months now, so i don't think I'm adjusting anymore. My periods are around like 30 day cycles, if that helps & we don't use a condom anymore.
