Anybody want to guess the gender? 12 weeks and 4 days NT scan. We've had numerous scans and we haven't seen anything down between those legs! I'm hoping this ones a girl, I already have 3 boys! One shot is from top looking down and the other is the profile shot with what might be the nub? We aren't sure because it hasn't been in any other picture! The other picture is just a clearer profile but the "nub" isnt there, hence why we think it might just be the cord!
