Sneak peak test at 8 weeks

Alexis

Hi everyone so I found out I’m just bout 8 weeks and 5 days pregnant. I bought the sneak peak test and you can do it as soon as 8 weeks. So I’m just wondering does anyone know around what week if the baby is a boy when would he start forming the genitals ? I googled and it said around week 9? I just wanna make sure before I take the test and it may give me a wrong answer lol. Thank you all!
