Period For 2 Weeks Straight????

Nymph
I think it might be the birth control though. I took the pill for a whole month (just one pack) and then I stopped and decided not to take it anymore. So when I got my real period, 4 weeks later, I've bled for about 6-7 days but 2 weeks later I'm STILL spotting... its mostly brown but sometimes it looks like blood! Oh and I keep getting those nasty blood clots that we usually get when we on our period. What is this? What does this mean? It's Soo annoying and I dont even know if im fertile or not because I keep getting brown and red spotting. What could this be? help me!!
