Family Planning Plus

As long as you took your pill within 24 hours of missing it, your pregnancy risk is very low. While you are on the pill, you do not ovulate. Missing a pill by over 24 hours and especially missing your very first pill in a new pack increases the risk that you might ovulate and thus increases the risk of pregnancy. Women who use the pill perfectly (take a pill at the same time everyday) have a 1% risk of pregnancy. If you missed your pill by less than 3 hours, you would have the same risk. If you missed your pill by more than 3 hours, you would have a slightly higher risk.
