Looks like a boy right ? This is my sons 20week ultrasound & it shows his butt/legs & what's suppose to be his penis .... I'm kind of paranoid because I've been having dreams of having a girl. This looks like a penis right ? not a finger or his umbilical cord, his hands were by his head when this was taken Btw ...
