Prolonged Menstrual

I have had my period twice this month. But this second one has not ended. It is going on NINE days already. I started birth control for the first time a month and three weeks ago; could this have anything to do with it? I wanted to be regular but this is still very abnormal for me and not something I want. I just want the bleeding to end! It's not heavy, it is actually a little more than just spotting.
