pink discharge

I stopped taking my monthy birth control a little over a week and a half ago, and a few days later I had my normal cycle which stopped about two days ago, and today I've been having light pink discharge which started with a odd cramp (not a menstrual cramp either it felt more like one of my overies hurt) it's not a texture or consistancy i've seen before. Even when on my birth control I was sexually active and I wasn't taking it consistantly at the same time. So would anybody have any answer what on earth is going on? I'm not sure what's going on with me.
