Hi, I'm 24 years old and a mother of one. I'm currently on the Othro Evra birthcontrol patch, I have been on it for two years. I started my period on Tuesday morning... it was brown discharge all day on Tuesday; it turned into a light flow of bright red blood Wednesday through Thursday. Friday (today) it's very light and pratically gone. I've taken a pregnancy test and it came back negative. I'm still not convinced. What does a period like this indicate? How soon should pregnancy be able to register on a pregnancy test? Could it be the birthcontrol causeing a lighter period? Any insight would be greatly appreciated.
