Hello, I started my pill pack one day earlier than usual, on Friday instead of Saturday. My period will therefore arrive one day earlier, on Sunday instead of Monday. How can I go back to my previous cycle without compromising my protection?

It is important to not interrupt your contraception for more than 7 days, as this could lead to ovulation. I suggest that you take a 4-day break and pick up your new box on a Tuesday, followed by the next box on Sunday.
