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.

After taking your gender predictor test and finding out I was having a boy, I was very excited. Couple of months later when I got the ultrasound, the doctors told me it was a girl. One month later, they told me that it was a mistake and I was really having a boy. Your gender prediction test was accurate from the beginning. Thank you very much.

Oh my gosh! You were right! I took your baby gender predictor test about 2 months ago and it said that I was having a girl, Nobody believed me and today I went for my 20 week ultrasound and the tech told me that I was having a girl. I'm so excited and I want to thank you!!!!!

On Nov. 18, 2006 I took your baby gender prediction test, even though I was extremely skeptical. You said that we were having a girl (we already have 3 boys) and I figured we were more likely to have another boy. I did not want to get my hopes up. On Nov. 27th and again on Jan. 24, 2007 I had an ultrasound that said we are definitely having a GIRL!! I was so amazed that you were correct so early in the game! Thanks and I will recommend your site to others!

I just wanted to say thank you, thank you, thank you, thank you!! You were right about my first being a boy so I used your 4 year plan to plan for our second, and despite all chinese charts saying it was a boy your site said girl and I found out today at our ultrasound you were 100% right, I could not be more happy, thank you!!! If I have anymore children I will definitely use your site again, you guys are amazing!!!
