Sneak peek accuracy

I have been seeing a lot of people comment that their sneak peek test was not accurate. I did mine at 6w4d and my son and hubby were not home. I made sure to sterilize everything and make sure everything was clean. I did the at home “fast track” version, and I got a boy result. I feel like it is accurate but I am worried now because I have seen a lot of posts saying it was not. What are your thoughts?

Hoping for a boy 💙💙💙 what are my chances that it was correct? 😩
