any December moms babies still breeched ?

Nadia • FTM , due 12/23 with baby boy
I'm 33 weeks tomorrow and yesterday at my appointment my dr. Told me baby isn't head down . She scheduled an ultrasound when I'm 36 weeks , if he still not head down then she's going to schedule a c section .
I'm just wondering how are you other moms doing or your experiences with past pregnancies.
I know baby still has time to move but still concerns me
