You're at your first trimester

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.

Just wanted to thank you and say you were right I/m having a baby Boy that/s due March 31 I did the gender predictor test on September 20th and I just did a sonogram on November 4 and it showed it was a boy I would recommend your site to all my pregnant friends ....thanks again.

Just a quick email to let you know that I am 17 weeks pregnant, I have been experimenting with the Chinese gender selection and so far they have been all right!. My three daughters were predicted as girls, it now predicts I will have a boy, I also tried it on my sister, at the age of 35, other Chinese calendars predicted her having a girl, fortune baby was the only one which predicted a boy for that month, last November she gave birth to a lovely boy!!!! so yes! your calendar is 100% accurate!

I took your gender prediction test in July 2009, and it came up with GIRL. I was a bit skeptical, and took a urine based test that clearly showed BOY. They will not tell you the gender on ultrasounds in our town, so I had to wait until November to find out, and it turns out I should have just gone on Fortune Baby's results after all--we had a girl! Thanks!

I took your baby gender predictor test when I was only 2 months. We already have a daughter and we really wanted a boy. I took your baby gender predictor test and you said it was a boy. Yesterday, I went to have my 20 week ultrasound and sure enough we are having a boy!! Ladies, this really works!!
