I've been really looking forward to the 20 week scan but it was awful. Scanner concluded everything was normal but with lots of negative comments along the way eg 'well it's legs are very short but they seem to be just in the normal range' and 'it doesn't seem to move very much'. She also said she couldn't tell the sex which I'd hoped to find out. Can I request another scan from someone else? Do you think I'd be reasonable to ask?
