3D ultrasound

Kvdc

Hi, I'm 32 weeks now. Next week I have an ultrasound scheduled , because my doctor says I'm measuring ahead. So when I called in the ultrasound department and asked about 3D ultrasound they just said you have to talk to the technician on that day. I checked with my insurance and they won't cover it.

How did people who got 3D ultrasound make appointments....did you ask the technician during ultrasound or schedule ahead
