Blood test

Maria

Hello everyone I was 10 weeks and 6 days when I did my blood test work through Myriad to see if there was any chromosome disease risks for my baby which also can detect gender! Well my result were low risk and that it was a boy my fetal dna was 4.7% at that time! My question is has anyone experienced a wrong gender through blood test? I’ve heard a few stories about them being wrong!
