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.

All other gender prediction sites, including chinese calendars, and all my friends were wrong about what I was having. Yours is the only website that said I was having a boy-which is what I wanted! Your site gave me a spark of hope and when I got my ultrasound done a month-and-a-half ago or so, it was confirmed that I was having a boy! I already have a son, William, and he is so happy that he is going to have a baby brother, Daniel, in March. Thankyou so much! I don/t know how you do it, but way to go!

Dear Fortune Baby, I took your baby gender predictor test with my first pregnancy and you predicted we would have a boy and you were correct! This time around you are predicting a girl and I hope you are right! I am only 6 weeks pregnant, but I am looking forward to my ultrasound. I will let you know the results. Thank you.

Just wanted to say that your gender predictor test was correct. I had an ultrasound at 20 weeks and they said it was a boy. When I switched providers they also gave me an ultrasound at 28 weeks and I could clearly see it was definitely a boy. I took you gender test for fun and it was right. I am so excited because I have a little girl and now I will also have a baby boy.

I just wanted to say thank you. My husband and I used your gender prediction test and was told that I would be having a boy. Everyone told me because of the way I was carrying and the fact I am Sick all the time that I would be having a girl. Well we just had our ultrasound and found out it's a BOY! We are so happy. Now we will have two BOYS! I can't believe it worked!!! Thank you again!
