Babys position

When is it to late for a baby to turn from breech position. Im only 32 weeks so i know the baby has time to flip but i just thought id ask from anyone elses experience when there doctor decided you would have to have a c-section.

PS im having an ultrasound at 37 weeks to get the estimated birth weight to make sure i can go through with doing a vaginal, because with my last son i had to have an emergency cesarean because he couldnt pass through, he ended up being 10lbs so they want to make sure this time around the baby wont be to big. So ill probably be finding out if the babys still breech then too.. Just thought id ask what other mommas experiences were. Thankyou again
