I started my period Nov. 14th of this year and ended Nov. 18th. On Nov. 22nd I started have brown discharge but it wasn't really dark just light brown and dark red. It is Nov. 28th and I have still having this brown discharge but it really dark. I'm worried, should I be? Can someone explain to me what it is and why it is happening? I have PCOS and stopped taking 'the pill' in Sep. 2011 or somewhere around there. My periods havent been regular for some time now. They come when they want.
