Business of being born

Ok so I just watched this documentary on Netflix and cried like 5 times.. I've always know I wanted to try for the all natural birth but now I'm even more convinced. I'm really freaking out about something wrong happening or the doctors trying to rush my labor and possibly pushing me towards a cesarean 🙁.. I do have an obgyn who so far has been nothing but awesome but now I'm wondering about birth centers and midwives.. FYI I'm 18+4 weeks. Any current mommies out there who can kinda break down their experience of birth centers vs hospital births?? If I choose to go the birth center route does that mean I have to have a midwife or can my obgyn deliver at a birth center??
