My sister was told at both her scans that she was having a girl, and all the way through she said she always felt like it was a boy, and when HE pooped out, he was definately a boy. From what I know, it is not possible at a 12 week scan to tell for sure if a boy or a girl, the genitals are only at a point where if examined outside the womb it could be told what they are, at that stage, on a scan a penis and and a clitoris still look pretty much the same.

I think the problem with a lot of scans is that if a penis cannot be made out, the sonographer sways more towards a girl, but bubs could just be in a bad position, or penis could be sort of tucked in between the legs. We were lukly with Jackson, we could see his bits plain as day at his 20 week scan, looked just like a little turtle sticking out between his legs, so I will be checking for turtles this time!!
