I'm 16 weeks (well 15 weeks 5 days) went in for our 4D ultrasound today. Baby faced my back most of the time, finally it turned, but then we couldn't get legs to uncross. We paid 70 dollars for a 15 minute 4D session, pictures etc. But we got to see the 4D for maybe 3 minutes altogether, the rest was like an ultrasound I get in my regular doctor office. After ten minutes of the ultrasound they just decided to reschedule us for a later date. They gave us pictures (not 4D ones like we paid for) and they weren't even of the baby (that I could tell at least) Definitely not something I'll be paying for again. Hopefully you ladies get better results, with a more patient staff in you decide to get a 4D. Vent over.
