Most painful part of giving birth?

I’m genuinely curious how it’s different for everyone!

I saw a Facebook post and very woman was expressing something different, and now I’m curious to know which part of birth was the most painful? Was it contractions? Was it the actual pushing? Was it your vagina? Give me all the details.

(I’m weirdly not scared of birth at all right now- I’m more scared of motherhood 😂 so don’t hold back)
