Hi. I was on birth control for about 7 months and stopped taking it October 16 2012. Today is February 17 & ever since I stopped, my period has been regular. I have a period app on my phone when I know I ovulate, period came and ended, and when I marked intercourse. This month however, I was suppose to have my period by the 9-12th day of February. I know when I ovulate, by the way. Anyway, on my period app, it says my period should come the 9th of February. Although, literally the night before, I thought I was going to have my period but I had a dark brown discharge with a mixture of dark blood that was odorless stained on my panties. ( and it was a good amount/ not spotting or a little stain.) I peed and noticed little brown skin that came out. My period is now a week late. Too include: last January ( last month) I had intercourse on my LAST day of my period. My boyfriend didnt cum in me but there wouldn t be any point if he did because I ovulated around 9 days later. Please help me why I am late and what this dark brown discharge meant that night. After I peed, it was long gone.
