I got a call this afternoon from my OB's office that the technician at the imaging centre couldn't get all the measurements and I have to go in a second time. The earliest they have is December 17th. Maybe we'll get lucky and have a technician who's more talkative and willing to show me more?
I'm a little peeved that the technician didn't suggest I get up and move around if she was having trouble or at least let me know at the end she needed me to come back. Sheesh.
My OB's office felt bad calling me, right off the bat she was like "No reason to worry!" because of course my first thought was my OB saw something and needed another look!

Re: So after whining about my a/s...
I am happy we get to go back again. This time I think we'll bring the video camera! I'm not sure that's allowed though. But hey, I didn't see any signs posted up that it's not and they have signs all over!
I will see about requesting a different technician, because when I had my 11 week ultrasound the technician was a lot more talkative (it was a different imaging centre though, too bad that one's not open Saturdays), but it's tough to say if they'd be able to accomodate me. This place is hopping busy.
ETA: Boooo, I just called them (it's still early here) and no video taping allowed and no requesting a different technician. Poop. When I explained my concerns, she told me things used to be different until the private ultrasound clinics opened up.
