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.

I just wanted to tell your site that I am in fact going to have a baby girl! This is my 4th child and I have 3 boys so when your baby gender predictor reading said I'd have a girl I was really skeptical. But I am indeed having a baby girl in June. You're amazing!

I JUST WANTED TO TELL YOU THAT YOU GUYS WERE RIGHT IT IS A BOY. I REALLY DID NOT KNOW IF I SHOULD BELIEVE IT. BUT MY FIRST ULTRASOUND THE BABY HAD THE LEGS CROSSED AND THEN I WENT ON YOUR WEBSITE AND IT SAID IT WAS A BOY. A WEEK LATER AFTER YOUR PREDICTION I HAD ANOTHER ULTRASOUND DONE AND RIGHT A WAY THE BABY DID NOT HAVE LEGS CROSSED AND SURE ENOUGH IT IS A BOY. THANK YOU FOR BEING A REAL PREDICTION. THIS IS BOY#2 THANKS GUYS.

I'm sure you get e-mails all the time, but I wanted to let you know that you were correct about the gender of my child. I entered my information when I was only 6 weeks along, and I had my daughter as you predicted in December. I definitely think I'll be using your predictor again when we try for a boy.

Dear Fortune Baby, On 12/1/08 I found your site my daughter was 11 weeks pregnant and I paid to find out the gender of her baby. When I keyed the information much to my excitement you predicted she was expecting a baby girl! I went to several other sites and they all predicted she was expecting a boy. My husband and everybody laughed at me and told me I was crazy. I went out and bought pink everything. Kristen had her ultrasound to day at 18 weeks pregnant and you were right she is having a girl! My son announced 3 weeks ago that he and his fiance' are expecting a baby 3 weeks after my daughter so I did the test for them and you predict that they are having a boy! They are scheduled for their ultrasound next month so I will let you know what the results are. I believe and everyone else should try your site as well. Thank you so much! A very excited Grandma!
