So I've been reading around to see how people have used PM as birth control. Apparently it is used in some birth control pills. I was wondering how effective it is as a birth control. I know some birth control if you take it continuously you will get a very light period or no period at all. Since mine tend to be very heavy and long I was wondering if I take PM up until right before I am supposed to get my period what kind of effect do you think it will have? Has anyone had any experience with this?
