Anyone else do the nub theory? And it be true

I done mine at 12weeks 1 day and got 80% chance girl and 20% boy because they said under 14 weeks boys can prematurely grow their genitals but the nub seems to be in line with baby’s spine so it’s edging towards girl more but I’m apprehensive now 🤣 I’m hoping girl I have 2 boys lol but either way I’ll be happy
