What's the best way to have a natural birth in a hospital?

re
I just watched The Business of Being Born. Even before watching it, I knew I didn't want any epidural or any pitocin or anything like that. I just want a natural birth. I'm having my baby in a hospital, and I'm 36 weeks pregnant. Should I refuse pitocin and things like that? What do I do to have an intervention free birth? PLEASE HELP💙
