Fortune Baby Gender Predictor Reviews

Thousands of happy moms around the world successfully used Fortunebaby gender prediction test. We are delighted to share their gender prediction reviews about their experience with Fortune Baby.

Hi all at Fortune Baby, I had my 22 week scan last week and I would just like to let you know that your gender prediction was CORRECT, my husband and I are over the moon, you predicted that we would have a baby girl and this was confirmed last week, we have two beautiful boys and this new addition will just complete our family, football mad boys for daddy and a little girly girl for mummy. I will definitely recommend your site to others. Thanks once again

hi just thought i'd drop you a line to let you know that i am having a girl as you predicted and also a boy. yes it's twins. once again thanks

Just wanted to let you guys know that this website is great! i have two boys already and very much wanted a little girl. I tried your site when i was about 2 months pregnant. You guys predicted it was a girl. I was very skeptical because everything else i did said it was another boy. I went for my 19th week ultrasound appointment today and you guys were right, I'm having a girl! I'm so happy i can't contain myself! THANKS!!!!!!!

I had your one year prediction test done, knowing that coming from a family where the last 13 births had been girls, I was of course desperate for a boy. Your gender predictor was that no matter what month in 2006 I conceived, it would be a boy. I got pregnant in May 2006 and in February 2007 gave birth to a beautiful boy! I am now going to find out what you predict for my next child. Many Thanks.
