Hand test for gender prediction?

Ok bare with me 😅 I want a girl so bad, I've done this test 10 times and it comes back with a boy first (which is correct) and then a girl and then no more kids. Has anyone done this and it be correct? anyone its not correct for? and finally anyone willing to try it to test for me lol I am desperate for this to be right, we are going to start ttc the end of February or early March so I want to beleive it so bad 😂

Heres the video I followed to show me how to do it:
