NIPT possibly wrong

I’m so worried my NIPT results are wrong… I already started buying baby girl stuff… I was hoping to confirm gender at my anatomy scan but the tech was crap and said the baby’s legs were closed so no confirmed gender through ultrasound… I’ve just seen too many stories of women having blood test but the ultrasound said a different gender and the ultrasound was right… I have a bmi of 30-32 I think and I had the blood draw at 10 weeks 2 days with a fetal fraction of 7.3%
