Birth Control

My boyfriend and I have been using a male condom and the pull-out method during sex, but I want to do everything I can to prevent getting pregnant. Not looking for criticism here, I just want to know what other forms of birth control I can use. Keep in mind my parents aren't aware I'm sexually active, and I'm turning 18 on February 8th. Thanks! 😊👻👏🏻 If possible, please provide full explanation how to use suggested method, and side effects, the whole nine yards.
