It is common for babies to be breech- some turn right at the 'last moment'. It really depends on your doctor, how long they will let you go for- some will let you go longer. Also, there are many resources out there to try to help turn the baby. Some doctors will go for this and other's won't- I'd recommend looking up some resources on that and having a conversation with your doctor to see where their expectations lie on this. Good luck!
I was pregnant with twins and one of them was breech up until labor. I was having labor contractions and went to the doctors and they said I had to get a c section. I told them to wait. And what do you know by the time it was time to push both had heads down. Pushed them out naturally with no meds. Beautiful.
