Depends: The least effective is the one that annoys you that you don't do/take. For some women, taking a pill is super hard, for others, it's easy, or they set an alarm. The most effective in terms of preventing pregnancies are the iud and the implanon. Condoms and withdrawal are the least effective at preventing pregnancy. But honestly, the best birth control is the one that you like and that you use!
