When Is The Best Time To Get A 3D Ultrasound?

Ni

I’m trying to figure out when I should get my 3D ultrasound...I want a good clear picture and don’t want the baby to be too squished and want a good photo of his face (fully developed) close to his due date. *Can I see everyone’s good 3D ultrasounds and when you got them done??* I’m 22 weeks now and was thinking about getting it done at like 30-33 weeks pregnant.
