100% a boy right??

This was 15 weeks 4 days, but he’s been measuring a week ahead. I’m a worrier & ive gotten used to the idea of having a boy & tbh would feel a tiny bit sad if they say at my anatomy scan that he was actually a she. I’ve just read a few stories of them getting the gender wrong that early but it looks so clearly like a boy i don’t see how there’s any way he’d turn into a girl in a few weeks 😂
