C-section or Natural

Miriam
Im about to be 40 weeks this sunday. My doctor told me my baby is still way up there and im only 1/2 cm dilated. He also said the umbilical cord might be preventing her from going down. He said he gives it 2 more weeks past my due date (sunday 25).
Or he can schedule me for a c-section this friday! I have asthma and its starting to get harder to breathe and do anything. Its my first pregnancy and im so scared of a c-section. What is the best decision? What should i do? I feel like a bad mother already since i cant make this decision 😞 help plz!
