Feel crazy loo

I'm not in a hurry to have baby im 36 weeks by first ultrasound 37 if u count LMP but I dont know whatever there lol it's weird they did this pregnancy so different. I like my dr but kinda feel like he is not all on board if that makes sense. My baby is measuring outside and inside 3 weeks ahead . Before my dr would have changed due date I have to have a csection unfortunately I cant push babies out. Anyway we had an ultrasound last week and babies head measured 41 weeks I was concerned cause that seems big considering that all of her everywhere else is on time . I asked today and he kinda acted like he didnt know what I was talking about :/ I feel like sometimes were numbers instead of patients ....
