For Fun! Skull theory??

[IslandMama85]

Hi again ladies! After getting 50/50 guesses from my 12 week scan (potty leaned girl, but nub - which I trust more - leaned boy), we got our anatomy scan done at 21w2d and chose not to find out! Though we had chosen to be Team Green again we have talked about peeking at our 3D/4D Ultrasound tomorrow...so I wanted to get some guesses on Skull Theory before we go in . The top pic is my June 2016 DS and the bottom pic is this baby!

Also, I wanted to ask if anybody had gotten small measurements at their anatomy scans? All 3 of my kiddos (B,G,B) were measuring at least 2 weeks ahead by the anatomy scan, but this one is measuring right on track except the head, which is 1.5 weeks behind. Is this common and I'm just clueless? Everyone on my birth board seems to have big babies (like I'm used to) from their anatomy scans, so I'm a little freaked out. Thanks in advance for all of your advice/experience/help.

Based solely on skull shape and your other pic, I would say another boy! I am not sure about the measurements question. I have not ever had that issue or even told measurements of the head. Praying all is ok.

Thank you so much!
