Breech baby at 37 weeks

Panicking now cos I’m sure baby is still breech at 37 weeks despite all efforts to turn her by professionals (masseuse and chiropractor) and my attempts with inversions, pilates, yoga, walking, etc. We even talked to baby (cos that worked for my brother and SIL!). Any hopeful recommendations for me? I’m ok with C section (as long as baby is out and healthy at 40 weeks) but obviously I want to do all I can to prevent this. If you ended up with C section, how did your birth plan changed?
