angel*mystic:Thanks for your guesses ladies

.I know I didn't get a perfect nub shot,but with baby upside down does anyone think a boy nub would dangle down?
If baby is upside down that usually does void the nub theory and generally 11.5 weeks is too early (for the first pic). If you had only one of these photos to post, you probably wouldn't have gotten such confident guesses, but all the photos taken together really do point to girl, it seems. The upside down photos show what appears to be a nub that curves back toward the body which to me would be very indicative of a girl. However, all that being said, it is still important to remember that nubs are never 100% 
Good luck at your scan! Keep us posted, can't wait to hear your news!!!
