Random question about ultrasounds and gender

[surprised]

So I want to show people some ultrasound pics, but I want to double-check that I'm. It inadvertently revealing the gender.

The pic is a profile of the full body, so side on lying on it's back. I don't think there is anything revealed, but there is a gap between the legs (like how the heart shows up as a gap).

Can anyone help?
