Hi, my Baby's 12w 2d nub was flat and now at 14w 1d my Baby's nub is still really flat and the Dr said he thought baby was a girl and he was 95% sure, unfortunately I am unable to add pictures not sure why (keeps saying failed) , I know it's difficult without a picture but I just wanted to know in general how accurate is a nub picture at 14 weeks.
Thank you!
