Your Baby
After 8 weeks as an embryo, the baby is called a "fetus".  The baby's 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 (10 to 12 weeks), using a special instrument called a "doptone".  For the rest of your pregnancy, all body organs will mature and the foetus will gain weight.  By the end of this month, the fetus is 4 inches long and weighs a little over one ounce.

Your Body
You may still feel tired and have morning sickness.  You may have headaches.  You may get light-headed or dizzy.  Your clothes may begin to feel tight around your waist and breasts.  Try pullover tops and skirts/pants with elastic waists.

Prenatal Care Guide
Visit your doctor for one prenatal care checkup.  You have a slightly increased need for vitamins and minerals to nourish your baby.  A healthy diet meets most of these needs.  You may have gained 3 or 4 pounds by now.  A woman who starts pregnancy at a normal weight should gain about 25 to 35 pounds.  Ask your health care provider how much weight you should gain.  Exercise can be fun and good for both of you.  Walking is a good choice.  If your health care provider recommends prenatal testing using chorionic villus sampling (CVS), it will be done now.  By the end of the 3rd month, the fetus is 4 inches long and weighs a little over 1 ounce.
