Thanks for your query.
is used to prevent ovulation. As you missed one dose and compensated it next day by taking 2 pills. Though you have taken your dose little late but still you have same chances of pregnancy
when you use pills promptly/regularly. So don't worry and read carefully instructions provided with your medicine.
If you miss one active pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.If you miss two active pills in a row in Week 1 or 2, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.
Hope it helps.
