First baby nub theory

[Poppyalice9]

Hi I just had my first scan yesterday and I showed my family and they said i should try the nub theory I’m not really sure what I’m looking for does anyone want to have a guess for me? I’m happy either way just thought it would be a bit of fun!

You may be better off posting on the Pregnancy board?

I thought the nub/skull theory was generally debunked as nonsense? I think it’s generally impossible to tell until a sonographer sees ‘bits’, even then they can occasionally be wrong.
