Nub or skull theory help (pic)

[pomadas87]

I have been googling both nub and skull theory but am none the wiser from looking at my 12 week scan pic. Can anyone help me please (and explain what I'm not seeing?!)

Rounder scull so I'd say a girl? X

Going on the skull id say boy. Looks very like my DS scans

Skull looks like a boy - flat forehead. And I think I can see a nub pointing up at an angle - boy!

I read that its a flat forehead for a girl?!

I have a couple more pics of that helps? I cannot see a nub at all and I can't tell if the skull is rounded or flat

Try posting on ingender, there's a lot of in experts on there who guessed my boy correctly

I will look into that, thank you

Update! I have my 20 week scan and I am still none the wiser. DH really really doesn't want to know the sex so we haven't found out... can anyone guess from this pic?

From your 12 week scan I would guess girl as I think there is a horizontal nub.

The nub theory was right for my girl and boy by the way!

I didn't spot a really obvious set of balls at my son's 20 week scan

Interesting!
I have to admit I have no idea what I'm looking at, very tricky to see!
