im in the same position now.

2 scans so far 1 @ 20weeks the other @ 27 which was 4d scan

both times they have said girl but couldnt be 100%

I really wanted to have another scan as everyone keeps saying its a boy which is now freaking me out as we bought girl stuff (i've left all tags on except for a few things which will be the going home outfit if we do have a girl)
