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.

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!

Thank you, I have two boys and I wanted to know if this one was a girl and you said it was and I have had an ultrasound today and you were right.

Dear Fortune Baby, I thought I was going to get an ultrasound at 20 weeks, but when my doctor said I can get one at 18 weeks, I was excited! So yesterday, I had my doctor's appointment and ultrasound at 18 weeks. I am very happy and excited to say that what you have predicted was indeed 110% accurate!!! You had predicted that I will have a baby girl and you are right on the dot! I already have 2 adorable boys, 3 yr old & 18 moths old, and now I'm having a GIRL!! How exciting is that?! Very, very exciting!! J A beautiful princess to add to our loving family, plus, May I add, I finally won't be outnumbered by testosterones in the family! YAY!!! LOL!! J I am very pleased and astonished on your ability and knowledge to determine the sex of the baby as well as predicting the sex of the baby. I definitely will HIGHLY recommend your site to my family, friends, & co-workers!! Thank you so much for your hope and inspiration and prediction!! Keep up the great and awesome work!! Thank you again, and May God Bless you and your families always.
