Last day of my previous BC's plecibo pills. I got my period 2 weeks into the first month of taking the pills but I am currently 2 weeks into the second month and no period. I don't know if this is no longer affective because I did not take the pills on the first day or what, but I don't know if I should stop taking them and wait for my period to start a new pack or If I should wait it out to see if i get my period on the white pills, the last two days of the month. Please help
