Bleeding while on Birth control????

Logan

I am currently on Setlakin (a continuous 3 month birth control) and I was told by my friend that is on the same pill that I would have some spotting during when my periods were suppose to be.... well my "period" was suppose to start on the 25th of august, and I started spotting that day and spotted for about a week. BUT its now the 14th OF FREAKING SEPTEMBER and I'm STILL(!!) bleeding?!?!?
