Chances of getting pregnant when taking birth control pill at same time daily and using pull out method every time?

Very, very little: Wouldn't worry. In real life, a woman properly taking birth control pills has a very low chance of pregnancy. Combine that with the "pull-out" method, and she will have very, very little chance of pregnancy. Life can be surprising sometimes, so in the rarest of occasions a woman in such a situation might become pregnant... but that's life.
