Oral bcp/bleeding: Today's oral bcp's are very low in hormones, so in some individuals, it is important to take them within the hour of having taken the previous active pill. Low estrogen in the pill may not last if the interval between active pills is much greater than 24 hours, which causes withdrawal bleeding. If this continues, stop the active pills, and wait five days and start a new pack but be very punctual!
