8 weeks pregnant!!! Gender tests?

Kay G • I have a 6 year old son and currently pregnant with my 3 technically as lost a baby two years ago. Hoping for a girl!
Ok this is something most want to know I guess but I'm interested to know if any one has tried those gender tests and been correct! Desperate for a girl and would love to find out soon as I can whether I'm carrying pink or blue?? Happy whatever as long as there healthy 😍
