If I took two pills on the same day during the month, should I start the new pack on the same day or do it one day in advance?

If you have taken two pills on the same day during the month, you should start the new pack on the same day as usual. It is important not to go more than 7 days without taking a pill. It is better to shorten the placebo pill period than to extend it. Make sure to take at least 21 consecutive days of active pills to maintain effectiveness.
