I would just like to let you know that I have two girls and a boy already, and as this was to be my last child, I bought the four year prediction test in order to conceive a boy. Today my ultrasound confirmed that it is indeed a little boy, and I just wanted to say thank you for helping me achieve this just as you did with my last baby which you predicted rightly a girl. You are amazing!
