Huge baby

Went to the Hospital today for a growth ultrasound (appt made by my doctor) and my son's head & belly are huge, but everything else is normal. I'm measuring weeks ahead & now I'm getting nervous because the ultrasound tech said she would be surprised if my doctor didn't mention a c-section because he's measuring so big & it's my first child. He's weighing close to 6 pounds, and I'm 33 weeks pregnant. Just nervous for the c-section! 😐
