I took my daily pill yesterday morning, and slept with my boyfriend early hours this morning. honestly, I hardly take my pill I m so forgetful and that lead me to have a period about 2 weeks ago. However my boyfriend and I have been together a few years and we ve decided to plan a baby. I don t know how to work it out.. I know the contraceptive pill stays in your system for 24 hours, however I understand that ejaculation stays in your system for 72 hours? So if I don t take my pill anymore, is there a chance I could possibly get pregnant?
