Chocolate, glad your scan went well and that you are doing well on the gd front. I am in the process of starting to deal with it now too and feeling better every day.
Here is the link to the skull thing For fun - Skull shape tells gender 92% accurate - In-Gender.com
In profile a females forehead should in theory be more upright. But like i say ive seen as many of each gender with either! When people talk about a females being rounder they are right but not in the sense of a profile shot which at 12 weeks is what we would be guessing on iykwim?! This would be wrong info from this angle IMO
