After eight weeks as an embryo, your baby is now called a fetus. The fingers and toes have soft nails. The mouth has 20 buds that will become baby teeth. You can hear your baby's heartbeat for the first time using a special instrument called a "doppler."
For the rest of the pregnancy all body organs will mature and your baby will gain weight. By the end of this month, the fetus is about four inches long and weighs just a bit over an ounce. The first trimester is completed at the end of third month.
You may still feel tired and be plagued by morning sickness. You may have headaches, or you may feel lightheaded or dizzy. Your clothes may begin to feel tight as your waist expands and your breasts become larger.
Visit your doctor or health care provider for your month 3 checkup. You need more of almost all vitamins and minerals to nourish your baby. A healthy diet is especially important. You may have gained three or four pounds or more.
The average weight gain for a woman who starts her pregnancy at a normal weight is a total of 25 to 35 pounds. Your health care provider how will monitor your weight. Exercise is good for both you and your baby; walking is a good choice.
If your health care provider recommends prenatal testing using chorionic villus sampling (CVS), it will be done now.
