Anyone any good at nub theory? 2 boys and last baby

[ThisOpalUser]

We have 2 beautiful boys already and as this is our last baby this time I’m really keen to find out what we’re having. Any guesses?

I guess boy 💙

Nub and skull look boy

It's a total guess but I think the head shape looks like a boy

Thanks for your thoughts - I found it hard to tell if nub parallel or not since spine is curved a bit

My understanding is skull theory old wives
tale but nub can be very accurate.

Will report back after 20 week scan
