Here is a good shot of the fetus and the "yolk sac" which is like the early placenta. It's amazing really to think of how fast everything grows and changes.
The fetus is already in amniotic fluid. The black area directly around the fetus is the fluid. Amazing! I'm just as excited as I was with Claire! I have been having some morning sickness, so I'm convinced it's a girl, as I heard that it's more common with girls, but who knows. And I'll be equally happy with a boy or girl. :)
