Conflicting Sneak peek/NIPT/and nub

ho

I took my Sneak peek clinically at an ultrasound office where they took my blood from my arm, not the at home kit, at 10 weeks 2 days. My results came back girl. Had my NIPT just 5 days later and the results say boy! My scan with baby measuring 12w4d shows a girlie nub, so I'm so confused! Everyone says to believe NIPT but with my luck I'm in the .01% or whatever it is that gets a wrong result. Anyone ever see NIPT be wrong for gender?
