curious... nub

im just a little sceptical maybe clutching ay straws... but i have posted my baby nub pic on a few forums and have had 95% boy guesses due to apparent stacking which yes i agree there are a few times in the video where it looks all boy but there are also instances where i see girl nub, the stacking on top seems to get longer and shorter, sometimes it looks longer than the bottom piece of the nub does and the times it does look very boyish it almost seems that half of it is hidden away so my question is could it be something else that has imaged? I cant find any nub pics that look even a little like mine so im assuming its not your typical nub anyway..here is the video clip. would appreciate you input, im so hoping for a girl, have 2 beautiful boys and a beutiful baby girl in heaven 💖 https://youtu.be/x9ahtioHOIU
