The first trimester of pregnancy is a time of enormous change. Knowing what to expect and what to do to be comfortable can help you cope with the transitions that accompany pregnancy. In the first month, some women feel tired and emotional; others feel energetic and excited. Still others feel nauseous, thirsty, hungry, weak, or dizzy. By the second month of pregnancy, most women feel pregnant. By the third month, some of the complaints of the first two months disappear. For instance, you may not feel as tired and nauseous as you did in earlier weeks. You may begin to show this month, particularly if this is not your first child, though most women simply notice that their pants do not fit as well as they used to.

Sometimes at the beginning of pregnancy, a woman is more aware of emotional changes-joy, ambivalence, doubt, and anxiety-than physical changes. A woman's emotional response to pregnancy often depends on whether the pregnancy came as a surprise or was planned. But even those who have been planning a pregnancy for months (or even years) may find themselves going through a major emotional adjustment once they find out they are pregnant.

Some women feel tremendously happy when they learn they are pregnant. Trying to get pregnant can be difficult, and when it finally happens, many women feel a sense of success, hope, and excitement about becoming a mother. It can be a wonderful feeling to know the baby inside you will depend on you for life and love during the next nine months and beyond.

A certain amount of anxiety can come with this sense of responsibility. You may find yourself asking questions such as: Am I going to be a good mother? How am I going to know what to do? Do I really want to change diapers and never sleep? Is childbirth going to be too painful? Many women feel guilty about being overwhelmed and worried about the prospect of being a mother. Other women worry because they don't feel an instant attachment to the baby growing inside of them. These concerns and doubts are normal.

No matter what your emotions are, you can count on having good days and bad days. Remember, your body is undergoing a massive hormonal upheaval that affects your emotional state as much as your body. Feeling overly emotional at the same time you feel nauseous and fatigued can affect your emotions from day to day-or hour to hour. These mood shifts are a normal part of pregnancy, particularly during the first three months-when your hormones are changing most dramatically.
