At this time, your baby weighs approximately 0.8 ounce (28 grams) and about 3 inches (7.5 cm) long. The placenta is growing and weighs about 28 grams or one ounce. Your baby looks like a tiny human at week 13. The baby's head is still about half the size of the body, but will proportionately even out to about of the body size by birth. The baby's intestines have been developing in the umbilical cord up until this point. The intestines will now be moving to the baby's abdomen. Also, your baby's vocal cords begin developing.

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 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!

Just wanted to tell you as so many others have, that we just had our sonogram done at 25 weeks and it said it was a girl, just as predicted. Everyone said it was a boy because that's all his family has ever had and I was carrying in all the classic boy myths. You were right though, a little princess is on her way!

Your gender predictor test was correct. It is a boy! I have two girls so I am thrilled for the new adventure. Thank you!

Just wanted to send an e-mail - to let you know that your gender predictors were correct. I still have a hard time believing it's true that I am having a girl after having three beautiful blonde haired boys ages 4, 2, and 1. When my prediction last month from Fortune Baby said I was having a girl - I was hopeful but thought in the back of my mind that this baby will probably be a boy as well. That would have been fine since all anyone can really ask for is a healthy child. Although, I have always longed for a daughter and knew this pregnancy would be my last since I just turned 37. So - I found out this week at my 18 week ultrasound that I am in fact having a baby girl. I am giddy and totally over the moon. This is the best birthday present I could ever ask for. Thank you so much Fortune Baby! I feel so completely blessed and happy!
