I'm another one that mostly uses BC for period control. Started when I was in college. My cycle varies 28 days to as much as 60 days, so I started BC pills. Here's the thing for me I cannot take most of the generic BC pills because they make me sick. I've never had a problem with the name brand ones. The one I'm on now I actually can take the generic which is nice for the cost savings. I'm on one of the seasonal pills now.
