So my last period ended on the 26th of september i took 2 birth control pills then i missed placed it, so i didnt have birth control for 2 weeks my girlfriend had a few extras and i took 2 out of one of those packs and found out they were expired since march so i stopped taking those!! we had sex several times before my girlfriend gave me her birth control!! now my period is a week late, could that be because they taking birth control and stopping twice? or is a text recommended now? or give in more time?
