I'm scared 😫

I'm expected to have a 9, possibly ten lb baby.. not only that but he keeping flipping back to breach! It seems like every time I have an ultra sound hes just back and forth from head down to breach. I'm not 37 weeks and hes breach again. Doctors are suggesting doing a monitored procedure thing to get him to flip head down but I feel like its pointless because hes stubborn and will just go breach again. I'm terrified of having a c section. And I'm terrified of trying to push out a ten lb baby. And I'm terrified I won't have a choice because he be breach when I go into labor. Oh man... anyone else have to experience this?
