Boy or Girl??

I fell down an Internet rabbit hole trying to decipher and understand all the theories or: Ramzi, Skull, Nub. My first ultrasound was yesterday 12w 3d is what the little alien measured. Little bugger kept its hand in its mouth and its legs tucked up close so I don't have ANY pics that are good for the nub theory but I wanted opinions for Ramzi and the skull theory! Thanks all!
