I had one at 39 weeks but it was by sheer luck that we were able go see him at all, and the tech only agreed as it wss my birthday. I agree with other comments that you should look in to private ultrasound places and see if any of them have prices that might be worth it.

I did mine at 34 weeks at a private ultrasound place.

U can go to a private ultrasound place and get those done ..! They can be a bit pricey but most places will do them up to 36 weeks
