you will probably be fine but it is always wise to use a secondary form of contraception (like condoms) if you are not taking your birth control pills consistently. being a few hours late or early on your daily pill really should not be problematic. it would be your decision to take plan b. i can't make that decision for you. try taking your birth control pills when your brush your teeth in the morning or evening. put a rubber band around your pill pack and insert your toothbrush as a reminder or set your cell phone to remind you daily to "take your pill".
had unprotected sex 1st day of my period but did not take my birth control the same time every day the week leading up. . to starting my period (so days 16-22). i'm on ortho tri cyclen lo. again i'm also on the first day of my period. do i need to take plan-b or should i be fine? just want to be safe cause while i did take a pill everyday these pills weren't always at the exact same time.
