Look's like a girl to me! I have an u/s from when I was 12-13 weeks and pg with a boy, and you can see the 3 round circles Losingmymind is talking about.
Yea looks like a girl! When I saw my little girl's parts on ultrasound, they were a bit swollen, but there was nothing sticking out like my son's ultrasound was. Congrats!
