spotting

Okay so me and this guy had sex and we used a condom. But i kinda freaked out and thought the condom broke but i'm pretty sure i was just really wet. Anyway, we got plan B just in case and a couple days after i took it i started spotting and that's normal. then it turned into a full blown period for a week and i'm still spotting. is that normal?? i've been bleeding for almost two weeks now, and i think its cause of the plan B. idk helpppp
