So I've never been on one of these types of pages. I'm really concerned and nervous. I'm a track athlete in college and don't know if extreme workouts my be the reason why. I was completely done with my period for two days. Then walking to class I felt like I started again. So I rushed to the restroom and my underwear was covered in blood. But it seemed to be old blood. Is this normal or has this ever happened to anyone else!. ):
