Gallbladder attack vs Contractions

I have a question!!! Have any moms on here had gallstones before and can compare it to contractions?

This will be my third baby and I’ve had epidurals with my last two babies. My last epidural I had was horrible so I was considering an unmedicated birth this time. But I was curious how the pain of a natural labor is compared to gallstones. I’ve had my gallbladder removed before and that pain was horrendously horrible. So I’m thinking if I can go through that maybe I can try without an epidural 😂 idk. Any thoughts?
