Spotting for 6 days!

I'm up to day 50 of my first cycle after coming off birth control. I ovulated really late and I have been spotting now for 6 days! I've been waiting and waiting for it to turn into AF but no luck. The spotting began the day before my AF was 'due' and has just stayed. It's mostly brown but some has been red. Not sure if I count this as my period or not. Any ideas?
