To do or not to do 3D ultrasound!

Peaches
So I'm 20 weeks and 6 days I was wanting to get a 3D ultrasound I know no time is to early but I really don't want to waste $100 and my baby still unrecognizable or still doesn't have enough baby fat. So do you all think 21/22 weeks to early to get a 3D? Can I see your 3D and tell me how many weeks
