I go to hospital in 34 week than doctor says baby head is down now i am 39 week pregnant but not start labor pain can baby change position these days?

Breech: Rare to have the baby change from vertex to breech at 39 weeks. Not a lot of room for baby to move at this time except you have a lot of amniotic fluid around the baby which will expand or create a lot of room for baby to flip from head down to buttocks down. It is expected that labor pain will start anytime. If not after 41-42weeks most places in the usa will induce. Good luck.
