Young and needs birth control 😅

Alright, I know I am probably going to be judged. I am 15 years old, and my long term boyfriend and I continue to have unprotected sex. We use the pull out method, and he does very well. We have never had a close call. However, I would very much like to get birth control in order to ease my mind at times. My parents would never agree to it (they would say I'm too young) and my nearest planned parenthood would take 3 1/2 hours to get to by bus. Is there any way to get birth control anywhere else? I want to take responsibility for my actions and stay safe while doing it.
