you will most likely be well-protected. being late by 12 hours is unlikely to reduce the level of contraceptive protection (about 99%) provided the pill.
28 day birth control pack took last active pill 12hrs late. will i be protected once i start new pack. i am usually very good about taking the pills on time. on saturday night last active pill night i forgot to take the pill. i realized and took it when i woke up sunday morning. i see my boyfriend this coming saturday and will not be having any sex until then (one week after i missed the pill and right after my placebo pills/period week). will i still be protected?
