Sneak peek testing

Has anyone done sneak peek gender testing before 8 weeks? I was 8 weeks but when they did my ultrasound I was measuring 7 w 3 days, when I told the clinical lady I still felt like it’s was a boy (results said girl) she told me that since it was before 8 weeks the test could have said girl or inconclusive if there wasn’t enough testosterone & now I’m kind of freaking out. I’m happy either way, just wanting to hear others experiences.

I do have an ultrasound to confirm she is a girl but now I’m thinking there’s a chance she may be a he 😂
