Hmmm i'm not sure. Did she give you any indication of what that meant? I would think it sounds like a little fella you have there. When we had our 20 week scan they said it doesn't look like there is any boy bits and then when i had a scan a couple of weeks ago she said. yep def a hamburger down there, referring to the typical 3 lines they look for if it's a girl.

Good luck. Sounds to me like you could be getting a little man though.. YAY!!!
