16 weeks potty shot: how certain is a boy prediction?

[Trudy1019]

Potty shot - measuring 16 weeks 5 days sonographer confirmed boy which is fine but on all my 3 boys I could see a willy is this definitely a boy 🙈

Hmm looks female to me- like a burger side on! My boy had a clear testicles and penis was sticking out but it was at 18+1.

On my boys I could see a full on Willy or on my youngest I seen a big ball on the end indicating boy I’m just confused x
