I agree. There's just no arguing with it I think. Of course the nub theory is NOT 100 percent. But it was also correct for my first baby. I've also guessed many scans correctly. Probably around 5 in real life. But who knows ! Sonographer told me it's about 60% accurate to use the nub theory. So this one is likely to be a girl ( 60 percent ). I'll come back and update once I know !
