Can 16 week gender scan be wrong ?

Vann

Hi all, just wondering if there is a possibility of having it wrong. I went for a limited anatomy scan at 16 weeks 3 days and was told its a girl. I am little disappointed and thats why I am not fully convinced and have this feeling from the beginning that its a boy..

Are scans at this stage 100 %accurate ??

Please share your experiences..

Thanks..
