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.

Hi I was just writing to let you know we had our ultrasound yesterday and our baby is a boy!!!! That is what you predicted , we have three girls so this is pretty exciting for us , thanks so much for your gender predictor it gave us a little false hope until we found out for sure.I will sned all my pregnant friends to your site. Thanks so much.

Wow, I cant believe your gender predictor was right! I had my 20 week scan today and found out we are having a baby girl! After having four boys, we are so so happy. You predicted we would have a girl, you were right! Thank you!

I recently found out I was pregnant with my fourth child. My other pregnancies were all boys. So I was desperate to have a girl. I took your gender predictor test and it said that I was having a girl. I went to get my ultrasound a week later and sure enough (clear as day) it is a girl. Thank you so much. I recommend this formula to anyone. Thanks Again

We had our ultrasound today and it was a girl, same as what fortunebaby gender predictor told us. We are excited but at the same time we are little worried that maybe the ultrasound was wrong. I/ve heard horror stories about that. The technician told us she is 90% certain it/s a girl. So we figure if we add that to your gender predictor test results, it's pretty likely we/re having a girl, which we/re super happy about. :-) Thanks again!!!
