Such a dilemma... We have pelvic presentation. Today I had an ultrasound, the diagnosis was confirmed. They say we can walk until 40 weeks, then if it doesn't turn around, cesarean section. But I don't understand why there is "IF". CAN WE NOT DO A CESAREAN SECTION EARLIER? What if my labor starts? And what? I don't want to give birth in a pelvic presentation, it's dangerous! And what should I do? To insist on a cesarean section earlier? Or????
