For me labor. I had full back labor (again.. omg) It was only 2.5 hours from the beginning to his birth and for me it was too fast! I didn't have time to mentally prepare myself for the pain, the contractions were also extremely strong from the get go so I didn't have time to find a rhythm. Pushing took 10 minutes or so. I screamed off the top of my lungs since the pain was all in my spine but it wasn't long at all so I'd say I could do that again!
