I have been on Tri Sprintec birth control for over two years and never had any problems. I take the pill every day between the time of 7-8. I have been with the same guy for over four years, and am sexually active but we always use another form of protection. (Condoms, pulling out, etc.) I am scheduled to start my period in 8 days (Sept 15) but two days ago I noticed this brown discharge when I wiped, it had a tint of red in it for a few hours then went back to a brown color. Can someone please help me and tell me what's going on?
