I am 17 and have been on the pill for almost a year. My last period lasted for two and a half weeks. That have never happened to me before. I am not supposed to get my period for another week, but today I went to the washroom and there was blood everywhere. This wasn't like my normal period blood, it was more like actual blood, as if I cut myself. There was so much of it. I took my pill a few hours late today and yesterday, but I've done that before and nothing happened. I don't understand what is going on.
