So most people have guessed a girl based on the nub theory but for some reason I'm convinced it's a boy nub. If you look on the end it does point up (not the white line the actual end of the nub)

now do we go by the base of the spine? Because also baby spine is slightly curled at the end I'm going to put two pictures up and show you what I mean and maybe I can get some opinions.

Second pic I'll post below!!!!

Thanks in advance xx
