Contractions, Labor?

Crista • Due August 19th with my baby girl Miss Vienna Dianne.
I've been having these consistent contractions for over an hour now. They last like 30 seconds and when they peak the pain is a strong 10! They hurt like a bitch and all I can do is scream 😭 I'm 38.6 weeks and have a c-section tomorrow afternoon because baby is breach. I've never had painful contractions like this at all. My sister is trying to get me to go to the hospital but I really don't want to go to be sent home to come back tomorrow. No mucus plug, no bloody show, no broken water. Just these terrible contractions. I need a second opinion, what would you do?
