I've been on the pill for eight months now, and recently went on antibiotics for a UTI. My boyfriend and I did not have intercourse during that time, and are planning to use a condom when we do have intercourse. I'm the type of person who would prefer to be double protected (i.e., pills and a condom) so we plan to wait at least five days after i stop taking the antibiotic before having intercourse at all, and then we will be using a condom. My question is, I only take the pill for six full days after I stop my antibiotics before my placebo week. Is my pill ineffective for the placebo week if I only take six days of BC pills after I stop my antibiotics instead of seven? If so, what can I do to remedy this, other than making sure to use a condom?
