13w5d potty shot accuracy?

[TwinMom2]

Hi, potty shot at 13w5d - any idea on gender and accuracy? Can it still change?

Potty shots aren't all that reliable at that point but I don't see anything that screams boy. Looks girly to me. Your signature says you're having twin girls? Did you find out from a blood test?

Thank ksmom. I went for a private scan and I was just querying this one as it looks so different to the other twin's potty shot, but also, some people with twins said that because there are 2, the growth of the babies might be a little slower than with a singleton and some had wrong genders given at more or less same gestation.
I know its just wishful thinking on my part, but I was just wondering if perhaps I'm missing something. Also doesn't look very boyish to me.
