I have been on the combination pill for 3-5 months. I have been diligent in taking it anywhere between 10-11 PM everyday. Nonetheless I am worried about my risk of becoming impregnated after having my first round of unprotected sex last night. Although my boyfriend did not fully enaculate in me. He did release pre-cum. Today I start my sugar pills. I'm a little concerned about not taking an active pill. I was wondering if I should get Plan B or start my new pack. What's the best course of action?
