I just started my second pack of the Sprintec 28 day pill. 4 days into the first week of the pack, I missed an active blue pill. Since then, I have taken every pill consistently and within the two hour window. Yesterday I had unprotected sex and am afraid some semen may have entered me, however my partner believes he pulled out in time. It has been 5 days since the missed pill. Is it possible that I can be pregnant?
