From what I gather you take it from the 8th day of your cycle, to the 21st. I've heard others say that you take it the day your period is over, then for 14 days. Since you're on BCP it should be really easy to tell when to start/stop. Plus since we don't usually ovulate anyway, I don't think it should make too much of a difference.
