Nub theory- I was wrong!

So I was under the wrong assumption with the nub theory because instead of looking at the nub, I looked at the legs (which I thought were the nubs lol) and thought okay this is def going to be a boy bec those legs 
 an't go more up than that! 😆😄 but looking at the photos, what do you guys think? I'm not sure if what I'm looking at is the nub but let me know your thoughts :)
