I cant figure out what i am looking at...at 12 week, toilet shots will not work in determining gender. At 12 weeks you need a profile of the whole body to find the "nub". if the thing at the left is the end part of your baby( saying if it is a profile shot) then i would say girl, do you have anymore? 18, 19 and better yet, 20 weeks is the best time to look at the potty shots.
