My period lasts seven days. There's only seven inactive pill so therefore if my period don't start right after the last active pill (21st pill) the days i have left for my period would be shorter. I don't like the fact that i can't have a complete period so can i let my period finish completely before i start on the new pack even if the inactive pills are finished? Would i stand a chance of getting pregnant if i do that? Also can i have sex when taking the inactive pills while waiting for my period to start? Please this info would be greatly appreciated.
