What is it like to be pregnant, and would you ever do natural childbirth?

This question is mostly for mothers, I would think, but if you have something to say then that’s good too.
Anyway, what is it like to have something living inside of you? Did you like the feeling? Was it strange? Would you do it again?

With natural childbirth, would you do it, or do it again? What would you compare the pain to?
