Has anyone been told their baby was one sex, to findout at birth it was another?

Hi, this is just out of interest and I have heard of girls becoming boys at birth. Are there any cases of boys (at scan) being girls at birth? We were told we are having a boy this time but we didn't think it was that clear on the scan, where as the last 2 boys where very clear they were boys. Lots of people think from the differences in this preg, size, carrying, etc. that this is a girl (or could be wishful thinking ). I saw a physic this weekend who has been right on everything else and past babies sex so far, and she is adament this is a girl. (As well as telling me I will be having a fourth child !! Not if I have any say in the matter, but thats another story.

I haven't heard of a scan getting it wrong this way. Are there any cases out there? Not that we have long to wait now as I am 35 weeks this week.

Thanks.
