Two tiny cells join together within your body and, from that union, an entirely new person is created. The many complex organs and structures that your baby will need for life develop in just a few short months. The changes in your body are no less amazing. But while the baby changes most rapidly during the first three months after conception, your body undergoes its most dramatic changes during your second and third trimesters. It is during your second trimester that your baby will announce his presence. Early in this trimester, you will actually begin to see and feel your abdomen enlarging in response to his growth. What's more, you and your husband will be able to feel your baby's movements through the wall of your abdomen. While many of the discomforts you experienced in your first trimester have probably begun to subside, the next three months will bring a host of new changes. Many of these changes will occur in response to your growing abdomen--and your growing baby. In the following sections, you'll discover what's going on inside the womb, how your body is changing, how to tell if something is wrong, and how to avoid hazards. You'll find tips for relieving the discomforts that accompany the changes in your size and shape. You'll also find information on exercise and childbirth classes. This information, coupled with your attention to good nutrition, can help you take good care of yourself and your growing baby.
