I just started taking birth control. I'm on this stuff called estrostep, and no one I know is on it. I started it about a month ago. I took my "dummy week" a week ago, meaning I am on the 8th day of my new pack. I started my period again yesterday!! I know it cant be breakthrough because I had the almost the entire time the first month. This is like a true flow. I dont know what to do or what it is. I have taken all of the pills at the same time everyday. I wasn't late and I haven't missed a day. How is this possible if I am taking the active pills and I had my period a week ago??

P.S. Could this be linked to the fact that I have never had regular periods?? Thats why I am on it now, to regulate it. I would go months without having one. If anyone knows whats going on please help!!
