Hi I've been on yaz for about 4 months I recently go sick and was given 6 days antibiotic treatment. My boyfriend and I had unprotected sex four days after stopping the antibiotics... am I protected? I just found out that the antibiotics lessen the effectiveness of my BC, I also took my last active pill today and was considering skipping the placebo... what should I do?,help I do not want to get pregnant right now.
