Version Scheduled for Tuesday

I’m 36.5 weeks and baby girl isn’t flipped. While there’s still time, I have a follow up ultrasound Monday and if she hasn’t turned by then, lll be getting an external version Tuesday AM. Just wondering if anyone else has any experience with them. I’m very petite and in pretty good shape and the doctor said that sometimes that can work against you but we’ll see. I know they’re painful but I do NOT want a C section and will do everything I can to avoid one.
