Breech at 33 weeks?

Hello all! I've just been to my doc appointment, everything is normal with my baby girl but the thing is, she is still breech. My doc said I still have time till 36-37 weeks to see if she can flip over... But I'm still worried.. I can feel that she pretty much stuffed in my tummy and she hardly has space to move around and I'm worried that she might not flip. I've heard a lot about VBAC but I dunno the pros and cons of opting for it... This is my first baby... Is anyone else on the same boat? Did your baby flip in the last moment? Please help!
