20 week ultrasound tommo - should I drink orange juice?

Ha ha ha -- that's exactly what I do before an ultrasound, to get him to wake up and do something energetic for the camera :) As long as you have enough liquid in there, it won't matter what the liquid actually is. In fact, for my 17 week scan they sued a level 2 machine and if that's what they have, you don't really need to drink liquid before you go in.
