I had mine yesterday, my doctor did the strep b test and checked for dilation. Apart from that he discussed fetal kick counts and when I should go to labor and delivery if I'm having contractions. It was very similar to my normal appointments.
Maybe getting checked for dialation, depends on your doctor tho. Im 35+5 and just got my group B and second test for HIV, idk why they do it twice, your doctor office may be different tho! Next week at my 36+5 appt I'll be getting checked for dialation!
