QNatal blood test accuracy

How many people have had the QNatal bloodwork to see babies gender and have it be wrong? I just got my results back today and I’m happy don’t get me wrong but I was definitely hoping to be having a little girl and had a gut feeling it was a girl but they detected a Y chromosome which means boy.

I’m just happy that everything has been healthy with the baby. And that I have my rainbow baby coming in October ❤️

I just wanna know if anyone had the chromosome testing and have it be wrong.
