Chances of NIPT being wrong for girl??

A

Baby #2 results are a girl!! Fetal fraction just 4.5%. My first born was a boy and my fetal fraction was only 3.4% and it was accurate. But one of my good friends is also pregnant and her NIPT at 6% said girl and she just found out at her anatomy scan she’s having a boy!! I’m freaking out- I wanted a girl SO bad and I’m so badly in my head that it could be wrong for me too 😭
