IT'S A BOY - probably!!

The sonographer told us he thought it was a girl, not that he could see any "girl parts" but because he couldn't see any "boy parts".

After he had completed all of his measurements he studied one view for a long time until we were really worried that there was something wrong with the baby.  Eventually he said "I think it might be a boy after all, he's opened his legs now and look".  We looked and couldn't see anything useful, but he said he was "95-99% sure it's a boy".

The only sure way to know is to see the baby when it's born.
