how far along should you be for a 3d ultrasound? & is there a limit to how many ultrasounds you can…

14 weeks for 3D/4D gender ultrasound, and yes there's a limit because your insurance won't pay for ultrasounds "just because," the doctor has to have a legitimate reason.

would it cause harm the more ultrasounds you do in the pregnancy?

I had one at 21 weeks & it came out perfect. how far along are you? there is also places you can go that you pay for yourself to get ultrasounds done.

26 weeks today. my boyfriend really wants one and I know price ranges vary.
