So, just because I'm curious and I haven't had the chance to ask my doctor... I've been taking my birth control for about 4 months now. I take my pill every day in the evening before bed, but the time varies. Usually it's between 10-11, but sometimes it gets stretched out further (latest being 2-3am) does it really change the effectiveness of the birth control if you don't take it at the exact same time every day?
