Okay so i got what looks like to be it on November 9th, but it was really light but it had blood clots and I did have unprotected sex like a few days before but I took plan B and I know it was stupid. I also started birth control pills when I thought I started my period, but this is the 9th day and I'm still bleeding? Should I be concerned? The 7th and 8th were really dark like brown and right now it's really light red but not pink blood?
