Well I had my 1st Tri screen this morning but baby will not move even after me doing jumping jacks so I have to go back and try again lol so You guys think boy or girl?  The really white area by the butt is part of his/her spine I guess and not the genitals they said. The light grey are right above that really white area is the genitals. I'm 12 w 1d today. Boy or girl? rey area right above that is the genitals. Any guesses?
