Sneak peak test clinical

I was so excited I finally am having a boy and a cousin quickly told me I’m sure it’s wrong I’ve seen so many YouTube videos where they come out wrong. I’m so annoyed I was so happy until she ruined my day now I’m like really can mine be wrong ? I went to a clinic and got it done at 9 weeks 1 day and it seemed pretty straight forward with a phlebotomist and all but idk. I hope it’s a boy now I’m like anxiously waiting for my ultrasound to confirm in a few weeks anyone else feel these aren’t reliable ?
