Wrong gender?

So I was told at 14w US “chances are it’s a girl” then this week at 18w+2 I had a different person do the US she went over so quickly I didn’t even see her going there and just heard her announce “XX”

I asked her to show me she showed so quickly and not even clear shot..

I am happy either way but the way she checked it just leaves me in doubt..

Is there a chance I was told the wrong gender? Can you tell the gender from the pic?

This is what I was shown
