37 weeks tomorrow and baby is breech :-(

Kristin
My doctor thinks it's unlikely she'll move down into position. Going back next week for another ultrasound
If by next week she's still breech I have to either schedule an external version where they try to move the baby into position (I've hear it's painful) or I schedule a c-section.
Any techniques, methods, or exercises I can try to move her into position? Anyone successfully had their baby move?
