Yesterday was Serena's second scan. Everything seems to be OK - 5 fingers on each hand - 2 arms, 2 legs, normal size etc.
Here are two of the piccies - the bump above the baby's head is one of their arms and the one in front of their face is actually a leg! A bit of a contortionist!
Clicking them will open Flickr, where you can then click "All Sizes" to view them at a larger scale.
