Yesterday I felt discharge. So I went to the bathroom and there was a lot of brown discharge. Later that day I had brown and red discharge. So I put a tampon in.. Later on took it out and it was brown and dark red. This morning I put a new tampon in and it looks like my period. I'm confused on why this is happening. I had my period already this month... I know that brown discharge means old blood. Can anyone tell me what's going on?
