Sneak peak early gender?

Have any of your ladies used sneak peak to find out the gender of your baby earlier and if you did, was it accurate? I see the website says as early as 6-7 and a similar company “peekaboo” says as early as 7 weeks. Our (earth side) 2 year old boy was born with severe hypospadias and has had a total of 3 surgeries already with at least one more in his future. We were told the chances aren’t that much higher for another boy to have hypospadias with already having one boy with it. BUT I’m having so much anxiety over it and would just be a lot less stressed if I knew if this baby was going to be a boy or girl.

Any tips or reviews please!!
