Breech

Hey there! I had a growth scan today at 36+5 because at 32 weeks he was in the 86th percentile. He is now in the 69th percentile but the issue now is that he is still breech. Is it still possible for baby to flip head down at this point? this is my second and I fairly remember my second flipping late too but I can’t remember exactly what week. My doctor will not flip him as he said that he has never been successful doing so. Is there anything that I can do to help baby flip? Any other moms have a late flipper? My doctor wants to plan for a C-section just in case he doesn’t.
