Is 38w a bit late to check for dialation?

Vy
Hi,i went to a doc app on tuesday when i was 36w2d...doc did the ultrasound and told me that baby is in a head down position.Also did a blood work and group b strep test.I asked her about when is she going to check for dialation and she said when i come back in 2 weeks, i meant i see her every week now but why it gotta be in 2 weeks to check for dialation.Yesterday till now i felt a lot of pressure in my pelvic whenever i sit on a chair or when i sit on the toilet to pee.It hurts a bit.Am i close to labor?
