3D/4D ultrasound

Did anyone get a 3D/4D ultrasound done around 33 weeks ? This is my first baby & so I wanted to wait closer to my due date thinking we would get a good look at what our little guys gonna look like! But I guess 33 weeks is pretty late to do it since they are running out of room. If you did, how many weeks were you when you had yours done & did baby cooperate?
