Larin Fe 1/20

isabel

First time on birth control. I was given Larin Fe 1/20. I read the instruction but they are a bit confusing for me. I already had my period and that was on a Wednesday (Nov 2) and ended on a Sunday (Nov 6). So from what I understood I put the sticker starting the day that my period started? Yes I know I put the wrong sticker. Can someone explain when I’m supposed to start?
