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 did a prediction with you back in March I believe, and you were right. I am having a boy. Thanks!

Hi, I just took your gender predictor test out of curiosity. It was correct. I had an ultrasound determine that I am indeed carrying a girl. I will definitely recommend this site.

When I was four months pregnant, I went to the doctor to see what I was having, and my baby didn't want us to know what he/she was... then I was browsing the internet, and that's when I came upon your web site, and I put in the information that you requested, and you told me that I was having a boy, and then I found out I was having a boy, when my sister had went to the hospital to find out what she was having... and they told me a boy. Then on my birthday... I had my baby, and it was a healthy baby boy six pounds ten ounces, and nineteen in a half inches long! You are 100% right. I even did it with my sister's pregnancy, and before she went to find out what she was having... you told me that she was having a girl, then she went to the hospital, and they told her that she was having a girl! Thank you very much... I recommended you to everyone that is pregnant or thinking about becoming pregnant! You are the best... my son is 6 months old now!

I just wanted to let you all know that this gender predictor test really did work for me. I have 3 boys and I am pregnant with my fourth, the odds were against me so I tried your baby gender predictor test and it confirmed that I was having a girl and sure enouph I had an ultrasound yesterday and it confirmed the same thing a GIRL!!!!! Thank you so much, ladys this works.....
