So I've been on birth control for a year now, my pharmacy has been bad lately about refilling it before my active pills Are up, I wanted to skip my period but my pack wasn't refilled yet. Friday of last months period, I took it as a start date instead of Sunday. I have one pill left of this pack before my now period is suppose to start. I want to begin my start date on sundays again, so basically my cycle is off by just two days....I had unprotected sex yesterday. Since my period week is now, I'm covered right? And is it safe to start Sunday after my period is over, instead of doing the Friday start date.
