My last period was the 6th as normal. Ended the 9th. Also normal for me. I've been off birth control two months. I recently had unprotected sex but took plan b the next more. That was around the 14. Today the 21st, I had some brown discharge which seems weird as that two weeks after my period and still 2 weeks tell my next. What is it?! I really don't think I'm pregnant. I Finally got my new birth control today. But worried about what's going on. I also have zits every where but figured that because im ovulating right about now.
