Just for fun! Gender predictions? Nub/Skull theory

Okay just for fun! Have done my NIPT 11/12 and should hopefully find out before Christmas! Scan is at 10+6. I’m not great at nub or skull theory but I’m really hoping for a boy so I’m not as objective as I should be when interpreting the scan 🤣 I’m also not sure if nub is showing in scan photo 🙈 My interpretations of nub/skull theory below. Skull theory: Females have a gentler sloped eye brow ridge and rounder head, boys have a more pronounced eyebrow ridge and ‘blockier head’. Nub theory: If the nub is angled greater than a 30 degree angle in relation to the spine, it is likely a male fetus. If it is pointing straight out, under 30 degrees, or down, it is likely a female fetus!
