Boy lean. The forehead is flat and there appears to be stacking at the end of the nub.

Hi dear, it was 12 week 1 day... So What do you think is another boy on his way ????

I think boy too.

Can anyone tell or show me which one is nub please, I'm so confused. Because gender expert told me it's a baby girl , but everyone telling me here it's a boy .
