ok I have question. I was about a late week starting my period & I thought I was pregnant so I took a test & it showed up negative so I waited a few days & I finally started my period. It was very unusual, at first it was light & a brownish color & then the next day it was a very dark red & really heavy & lasted like that for about 2 days. Then it stopped for a day so I had sex & I started back bleeding again but this time it was different. Its an unusual pinkish color & I'm cramping kinda bad. Does anyone know what might be wrong? I've never had this to happen before
