3D/4D ultrasound

Joanna
At how many weeks did y'all ladies get 3D/4D ultrasound I've been wanting to get one done but I'm 32 weeks and don't want to throw away money if it's already to late...
**update: so my baby is head down already and it was way impossible to get the ultrasound done I checked in the hospital and was told he was head down so no need to spend significant amounts if he's literally squished
