For people that gave birth at a hospital/had a natural birth

I really want to have a natural birth (no medication whatsoever) at a hospital but I heard most of the time doctors push you to have medication to speed up with process even if you don't want to. For those that did give birth at a hospital/natural birth, were they pushing you that bad? And did you eventually give in after awhile? Also how to deal with the doctors that do push you to agree to go through with the medicine?
