First trimester of pregnancy


1st Trimester Duration: Weeks 1 through Week 13
fetal development

During the first six weeks, you may not feel any different. In fact, you probably will not know for sure until you miss your period. Then you may feel nauseous and fatigued. During the seventh week, the baby's development begins. He or she will begin growing eyes, ears, nose, heart and other organs. By the eighth week, you will be able to hear the baby's heart by ultrasound.

Gender Reminder

Did you know that you can find out the gender of your baby as early as you take a pregnancy test?

During week nine, the baby will develop bones, and arms and legs will take shape. At this time, feet and hands will be webbed. By the end of the tenth week, the baby will be small but fully developed. You may then experience more nausea and perhaps heartburn. During weeks 12 and 13, your baby grows quickly in size. Your fatigue may increase, and you may require more intake of food. You can now determine its sex through a sonogram, and see it for the first time at the doctor's office. As the first trimester ends, so does the dizziness, nausea and fatigue. Some women still experience nausea and heartburn going to the second trimester

Can you fly during first trimester?
It is best to always ask your doctor if it's ok for you to air travel during your first trimester. Women that have medical complications are not recommended to fly since there might be an increased chance of having a miscarriage.
First trimester nuchal translucency
Nuchal translucency scan is done between 11 and 14 weeks of pregnancy to help your doctor assess the baby's risk of having Down syndrome and some other chromosomal abnormalities.
Spotting during first trimester

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 purchased a baby gender predictor test when I first found out I was pregnant. I have two boys and have been desperately wanting a girl. The test said we were having a girl. I was excited, but still skeptical. Since then I have had numerous scans and now at 24 weeks pregnant we are definitely having a girl. Thank you and I will recommend this gender prediction test to others who just can't wait to find our and don't want to spend hundreds of dollars on a gender blood work test!

I used your gender prediction test (and yes! you were right- it was a GIRL!) I wanted to put her prediction in her baby book.) Thanks so much

We just wanted to let you know we had our 20 wk sonogram yesterday and were told we're having a BOY!!! -- Just as you predicted!! We already have 2 girls so naturally (even after taking your baby gender prediction test back in June) we were still so convinced it would be another girl. Several versions of the Chinese calendar also said girl. Of course, our first concern has been a healthy child but this news has put us over the moon! I will most definitely pass along your site to other expecting friends. Thank you so much ... we couldn't be more thrilled!!!

Your baby gender predictor test prediction said that I was having a boy but I was a little skeptical. I had my 20 week ultrasound yesterday and you were absolutely correct! There is no doubt that I am having a son. I will definitely use your website to plan for a girl next time. Thank you Fortune Baby.
