Is that the nub?

Ashley • 31, married 9yrs, together 16yrs We have a beautiful daughter who is 8. 3 Angels in heaven. Trying for our rainbow!
Is that the nub I'm seeing? If so can anyone tell me if it's boy or girl nub? The wait to 20 weeks is just killing me. Just curious for fun :) 
11w2d this was taken during our NT scan. Can't wait to meet our little rainbow baby
