### Human:\nhad 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.\n\n### Assistant: 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".
