We opted to find out the sex of our baby (privately - as our local NHS hospital will not tell you)
I went along at 17 weeks the sonographer thought it was a boy but wanted us to come back in a week later just to confirm as the baby was being a little bit difficult.
So we went back at 18 weeks and saw a different sonographer and she thought it was a girl 
So we are going back this weekend for someone else to have yet another look and see what the baby is...
But it's driving me insane with curiosity!
I really don't mind what the baby is, if anything being a boy then a girl it's made me just as excited about whatever they turn out to be.
So logically (or maybe not) I keep thinking that it must be a girl because the baby would have been a week older and easier to see?
Anyone any ideas?
I know it's only a few days until I find out, I just can't stop thinking about it! And it's been lovely to see the little baby so much and we've got tonnes of pictures :D
