How effective is the pill?

ANSWER

Birth control pills are considered effective, but not entirely foolproof. They’re about 99% effective when you take them correctly.

But that’s if you take them perfectly, meaning at the same time each and every day. If you don't, your odds of becoming pregnant go up to 9%.
