Look into your insurance and find out how many they pay for. You doctor may do it if you ask but your insurance doesn't have to pay for it.

How will they check to make sure she is turned correctly for birth??

Probably not unless it's an emergency or medically needed!

My doctor only does one after the anatomy scan if there is an issue. I had one today at 36 weeks because I barely passed my glucose test so they wanted to check his size. Otherwise, it would just be my appointments.

I had one at 40+4 weeks to check on everything
