Breech baby what to expect?

My sweet baby girl has been head down my entire pregnancy up until last week. I'm 34 weeks and had an ultrasound last night. I thought baby flipped and ultrasound confirmed she is breech. I know there is still time to flip but I'm wondering what protocols are in the case she doesn't flip? If I have to have a c section, when would it be scheduled? This is baby number 5 for me. All my other babies came naturally. Baby number 3 was head down until 35.5 weeks. The others stayed head down most of my pregnancy. I see my doctor on the 14th. Just curious in the meantime what the rest of my pregnancy may look like.
