Glad the scan went well sarah. So obviously my post is a little late for you....

My instructions for my morphology scan are to drink normally throughtout the morning, but not to go to the loo any closer than an hour before the scan.

At my twelve week scan I drank a 750 ml bottle of water 2hr-1hr before the scan and was told my bladder might not be full enough and that I was probably a little dehydrated. I'd also had a 500ml orange juice 2.5hrs before the scan!
