My periods have always been irregular I am 17. Last year I was put on birth control, took it a month and stopped. I hadn't had a period since June so I took a weeks worth of the pill and then stopped. Two days later my period started, 10/2. It is now 10/11, and as of yesterday I thought it had ended because as of 10/9 it had gotten dark and slow. I got my shower earlier and I just went to the restroom and it is clear my period is not over. What should I do? I have never had a period this long..
