Is a 15 week gender ultrasound accurate?

Katelyn
So at 15 weeks I payed for an early ultrasound to find out the gender of my baby and then figured it would be confirmed during my anatomy scan. I was told he's a boy 💙 Well when I went to the anatomy scan this week they said the legs were crossed and they couldn't tell 🙄. Now I think he's clearly a boy from the above pic, but now I feel paranoid haha. So... my question is... this is a penis right?? Lol
