We didn't get the results at the scan - had to have blood test and weight done at the hospital afterwards, then waited for result in the post, took a few days. (Plus my scan was too late in the day for bloods to be done as the courier had already been so I had to go back the following morning - you think they'd make sure 12 week scans were earlier in the day!) But they took my mobile no and I think if the result had been bad they would have phoned.
