Question for Back Labor Mommies

I had the WORST back labor delivering my baby last month. I never had so much as a period cramp in my uterus during the whole 36 hour labor. It felt like the baby came out my spine. Baby was not sunny side up, but facing the correct direction. There was no clear reason why I had back labor. For those of you who have had multiple babies and back labor, did you have it for all your births? I honestly don’t think I can do it again if I’m in for anything near the same. I’m still having nightmares about it. 3 failed epidurals. I would have thrown myself out a window if given the chance. It was agonizing.
