Nub Theory - anyone willing to have a guess for me?

[Westcoastmumma]

I’ve heard a few things about the nub theory and despite my efforts I can’t work out if my 12 week scan looks more boy or girly. Anyone got any ideas?? I’d be really grateful, interested to see what people think :)

Girl

Girl?

Thank you for your guesses! I’ve been researching it and can’t get my head round it

I think boy- feel like there's stacking there

Might be a stupid question but what does stacking mean?

Girlie 🤍
