I finished my period on Wednesday, had sex Thursday, Friday, and Saturday. Saturday right after, there was some brown discharge, I figured it was from my period. Sunday, Monday, and most of Tuesday.. there was blood only when I peed, like I was just finishing my period. Now Tuesday night, is dark brown.. it looks like it usually does on the very last day of my period. I'm going to the doctor Thursday, but I was just kind of looking for a heads up!!
