To be honest I've not experienced anything that hurt as much physically, but all the time I was hurting I kept in the front of my mind, the pain was there for a reason. I wasn't in pain because something bad had happened or that I'd had a horrible accident. In fact it meant each and every painful contraction was bringing both my precious children closer to being in my arms.
I would however say that yes there is lot's of things that hurt more - they are the emotional pains that you can't control.
The pain of childbirth is all part of the miracle and wonderment.
Good luck for your birth, I hope it is all you hope it will be.
