The changes that occur in a mother's body will be reviewed by trimester. Everyone will experience these changes in different ways. Some women may not notice many changes until much later in pregnancy. Others experience very severe symptoms early on in the pregnancy.
Many women complain of feeling tired and emotional.
Others complain of nausea and occasional vomiting. Nausea is common but can vary in severity from a mild queasiness to a complete inability to keep any food in the stomach. In this situation, called hyperemesis, the mother may need to be admitted to the hospital. Thankfully, this is rare. Another change noted early in pregnancy is increased fullness and sensitivity of the breasts.
