all ultra sound pics look weird..lol. when we went to see the sex of my son, the first thing i said was "omg he looks like and alien!". lol. the nurse thought it was funny. Don't worry, your baby will look just fine and precious when she gets here.
Imagine being smashed up into a VERY tiny space and you might look a little strange too if someone was looking at you! When baby is born they will look a bit funny, but as time goes by baby will start to loosen up and look cute as all babies eventually do!
