When is a pill considered to be MISSED? I take my birth control at 10pm. In the past I've had instances where I've taken 4 hours late or have fallen asleep and have woken up the next morning and taken it (so we'll say at the very latest 12 or 11 hours late). The instructions in the birth control pamphlet always say missed pill. So is a missed pill taking it a few hours late or taking it a day past the time you should have?
