unmedicated birth or epidural?

i am literally TERRIFIED to give birth. i am about 4.5 months and i am a first time mom. i keep seeing videos of people having unmedicated births and being “somewhat” fine with it and then next thing i know i see a video of a woman just screaming her head off going crazy. i’d say i have about a medium pain tolerance normally, just looking for some pros/cons or personal experiences from other moms!
