They will take a urine sample & some draw blood for base levels. Depending on how far along you are, you'll hear a heartbeat. Medical history and concerns are discussed. It's mostly a chance to get to know the dr & clinic. :)
My Dr just gave me a pap, drew blood, gave me a quick ultrasound for dating purposes and answered any questions I had it was quick but great to see the peanut. Not all Dr do an ultrasound though.
