Yep, I've popped in a small way and I'm ten weeks now.

It's definitely not wobbly either. I can also "feel" my uterus when I raise my leg onto the bed to tie my shoelaces so I imagine it won't be long before it's right out there saying "helloooo ... look at me!!".

It does seem to vary widely between women. I know some people who haven't looked pregnant at all until they were almost due to give birth!
