harmony testing

So last week I did the harmony testing and I also wanted to find out what my baby gender is,I got the results today and they told me a girl but I can feel it deep inside it's a boy it's not like it matters but also I was reading that before 10 weeks it can give a false result well according to my doctor I was 10 weeks but I know when I got pregnant bc I was monitoring my ovulation and when I did the blood work I was 8 and a half weeks...
Idk I have 9 more weeks for my ultrasound but do yall really think it was early and it can be false bc everything else seemed like it was a boy and I feel it
