I am glad I could help some what
I have seen a few people with girls and they are quiet small... more so just out to the sides and high up.
We found out what we were having too... it was pretty accurate... I could see the little pee pee and little sack floating about with my own eyes so it was pretty convincing...
It must have been frustrating when you realised they were wrong!! It would have been quiet a re adjustment!!
Now that I have thought about it I would have been right ****ed!!!

And it might just be the way he is sitting in your belly thats making him look lower than before?
