Birth control pills are actually pretty amazing. What does birth control do? Typically birth control pills contain estrogen and progestin (if taking the combination pill). These two hormones make the body stop ovulating, which means no egg is released.

The lining of the uterus changes as well which makes it harder for an egg to attach.
