Just curious.

So I was online looking up gender prediction things. We started trying a month ago and well we think that I might be but have to wait a couple more day to start testing. Well he really wants a boy and I found this at house urine rest that can predict gender as early as 10 weeks.  So I am just curious would any of you spend the money on this kit just to find out an extra ten weeks early and then just confirm by ultrasound????
