A 25-year-old female asked:

What happens if i miss a birth control pill in the 3rd week, take it the next day as soon as i remember, then continue my pack like normal (including the 4th week)? will that mess with my period? are there chances of pregnancy?

A progesterone pill only has less window of protection than a combination of estrogen and progesterone. Missing one pill should not undo the protection you have built up. As long as you are regular than no big concern. Nothing is 100 %, you can still get pregnant no matter what type of protection you use.
