Been taking pop pill (no estrogen) from the first day of period, which was a couple of days ago, if boyfriend cums in me, will i get pregnant?

Oral contraceptives: There are several important rules for oral contraceptives to be the most protective. 1) take at the same time daily; 2) do not skip a pill; 3) ALWAYS have a back up method. With this in mind, it is more helpful to use a back up method during the first week while you establish your routine. Therefore, pregnancy is always a possibility with a new user.
