36 w & 3 days Doctor Appointment SOS

Help. I just had a doctor appointment. The nurse took my blood pressure, took a urine test, and checked my weight. My doctor measured my bump and checked my sons heart beat.
(My doctor has been doing that for about a month and a half already)
I thought once you turn 36 weeks they would check if my son has turn yet???
How many weeks do you have to be till the doctor checks for that?
And are there others things you are supposed to get done???
