31 wks. Chances of babies turning

Bethan • Married 4yrs with 4yr old Boy. Pregnant with TWINS!!! after TTC 2 months. Very nervous about this time after awful pregnancy and terrible labour & birth.

Had scan today and Baby A is still breach. She hadn't changed position in 6 weeks. Baby B is transverse.

How likely is it she will turn? I really don't want a c-section. Has anyone got any experiences of baby turning later on?
