Talk to Gynecologist on Pregnancy

Please post this as ANONYMOUS aoa. i am a mother of 2 kids both delivered via c sec. Currently i am 37 weeks with my third child and my dr has scheduled c sec coming friday. my main concern is why cant we wait a bit more for surgery if there is situation. Gap between this child and previous one is 3.5 years. As i am a pollen patient and since last night i had pollen attack again so i dont want to have surgery this early. can any doctor guide me please?
