The first trimester is a time of many changes. For the first three months of pregnancy, you may also experience the most morning sickness, dizziness, and fatigue. Your mood may be erratic – you might fluctuate between feeling excited and happy about the pregnancy to screaming at your partner about forgetting to pick up a towel! Your body is adjusting to pregnancy hormones, and these are perfectly normal symptoms.

At the end of the first trimester, your baby is only about three inches long, and weighs around half an ounce. You won’t be able to feel any movement yet, but the baby will respond if you push on the abdomen. The eyes are on the sides of the head, but start moving closer. The liver produces bile, and the kidneys are functioning.

You can help prevent or lessen nausea by staying away from spicy and fatty foods. Eat smaller meals throughout the day, and sip on ginger ale throughout the day to ease your stomach. Take your prenatal vitamin in the afternoon or evening, as this can make morning sickness worse. The symptoms of morning sickness won’t harm your baby, but if you feel you’re losing too much fluid and becoming dehydrated, call your physician. This could be a sign of a condition called hyperemesis gravidarum.

At the beginning of your pregnancy, your uterus really presses down on your bladder. You might find you have to urinate much more frequently. If you notice blood or burning while urinating, see your doctor as this could signal an infection. While your uterus is starting to expand, you probably won’t notice much weight gain in the first few months. Your breasts may swell, and your stomach may protrude slightly, but it’s unlikely that family or friends could tell that you’re pregnant.

As soon as you suspect that you’re pregnant, you need to make an appointment with your caregiver. He or she will take a detailed health history, as well as doing a complete physical with a pelvic exam and a Pap test. Urine and blood tests will be performed, and your blood pressure and weight will be noted. Your doctor will talk to you about genetic testing – which is recommended if you have a family history of the disease, are over 35, or from certain ethnic groups where a certain condition is more prevalent. This is a personal choice between your partner, and won’t be performed until after your 20th week.
