You could always try the in-gender site aswell, they may know of a good way to get a clear picture posted. I've just relisted my pic over there with a clip on youtube aswell because I'm now wondering if I'm looking at mine completely wrong, whoops lol.
Angelface, Charliecats the ultrasound technician on there thinks that you may be carrying a boy! I'm gonna have to brush up on my nub guessing lol.
Here is a link to my youtube incase any body wants to have a guess for me!
