I am a little bit worried, but I don't think I need to be, searching for some reassurance. I began mercilon birth control pills the last Saturday of April this year, however I took my Monday pill (3rd pill) 19 hours late the next day so I took 2 pills on Tuesday. I finished that pill packet and got my 'period' during 7 day break. I started my second packet on Saturday last and took my second pill Sunday before having sex with my boyfriend without a condom but he didn't ejaculate inside me. Am I protected from pregnancy?
