Nub theory.. anyone got it wrong?

[Aneesa_09]

I have guessed from my 12 week scan I was having a girl because the nub was more at a straight angle rather than pointing upwards, has anyone guessed by nub theory and was wrong?

I know someone who was told girl in her 12 week scan by nub but was told boy at 20 week scan and yes he's certainly all boy! Don't buy pink till your gender scan! x

I have had 70 nub guesses so far in total - 60 girl guesses and 10 boy guesses so I will let you know on Saturday when I hopefully find out gender of my little bean! Xx

^ same here for me! almost 60 people have guessed girl based on the 'nub' on my scan pic (0 boys). My scan is tomorrow and I'm thinking boy, so I'll update as to whether everyone guessed it right or wrong x
