Before you become pregnant, it's helpful to have some basic information about what to expect. First, it's important to know that symptoms vary from woman to woman, as well as from pregnancy to pregnancy. Just because your mother, sister, or friend had morning sickness or intense craving during their pregnancy, doesn't necessarily mean you will too.
During the first three months (first trimester), you may experience symptoms like nausea, vomiting, and leg cramps as your body adjusts to the new baby. In the second trimester, you may find that your nausea improves. By the end of this period, you will feel your baby beginning to move. During the third trimester, the baby is putting more pressure on your organs as it gets bigger, so you might have to go to the bathroom more often and may have heartburn and swelling.
Good prenatal care should be sought as soon as possible. Your healthcare provider can give you resources and information that can get you on the right track in regard to diet, exercise, and your daily routine. He or she will also make sure you are aware of things that may indicate serious problems.
