How would you describe labor pain?

Sa

My son is head down and has been punching me or maybe head butting me in the cervix. It causes me a sharp and uncomfortable pain when he does it. (36 weeks)

I am wondering if labor is more like that or more like really intense cramps??

Like would you describe it as more sharp or more achy?

Asking just for reference. I think I could handle intense achy cramps but it if it is sharp pain like that sign me up for an epidural 🤣
