I went for my 20 week scan today and asked the technician if she could tell me then sex of the baby but she said she wasn't allowed to tell me. She said she could try to show me but I wasn't able to tell anything. I had left to wait for my picture but had to go back in from my coat and I saw she had written on the screen Gender - Male. I'm having a boy!!!! I couldn't be happier. DH doesn't want to know the sex so I have to keep it a secret but yay I got to know.
