A missed period may be the first sign that you're pregnant. You'll probably want to take a home pregnancy test and if that's positive, it's time to schedule an appointment with us.  A typical pregnancy lasts 40 weeks from the first day of your last menstrual period to the birth of the baby. Pregnancy is divided into three stages - the first trimester, the second trimester, and the third trimester.


In the first trimester (Week 1- Week 12) your body is undergoing hormonal changes that can cause:

Extreme fatigue, tender, swollen breasts, and nausea with or without throwing up

Cravings or aversion to certain foods and mood swings

Constipation or frequent urination

Headache or heartburn

 By the end of the first trimester, your baby:

Is about 3 inches long, and weighs almost an ounce

All major organs have begun to form

Has facial features, a beating heart and can make a fist

Has external sex organs to show if your baby is a boy or girl


In the second trimester (Week 13 – Week 28) you may experience:

Aches and pains in the back, abdomen, groin, or thigh.

Stretch marks on your abdomen, breasts, thighs, or buttocks.

Patches of darker skin, usually over the cheeks, forehead, nose, or upper lip.

Itching on the abdomen, palms, and soles of the feet.

Swelling of the ankles, fingers, and face.

By the end of the second trimester, your baby:

Weighs about 1½ pounds and is 12 inches long.

Can hear and swallow and is more active, so you will feel movement or kicking.

Has footprints and fingerprints and hair begins to grow on the head.

Has a regular sleep cycle. Lungs have formed but do not work yet.

If your baby is a girl, her uterus is in place along with a lifetime supply of eggs in the ovaries.

If your baby is a boy, his testicles begin to descend into the scrotum.


In the third trimester (Week 29 – Week 40) you may experience:

Difficulty breathing and the need to urinate more frequently as the baby grows
and puts pressure on your internal organs.

Tender breasts, which may leak a watery pre-milk called colostrum.

Hemorrhoids and swelling of the ankles, fingers, and face.

Feeling the baby "dropping," or moving lower in your abdomen.

Shortness of breath, heartburn, and difficulty sleeping.

Contractions that can be a sign of real or false labor.  

 By the third trimester, your baby:

Is gaining about a half-pound a week and storing more body fat.

Has bones that are soft but fully formed and eyes that can open and close.

Has organs that are capable of functioning on their own.

Has less space to move around and movements may feel less forceful to you.

Weighs about 7 pounds and is 16 to 19 inches long just prior to birth.
