In the first half of pregnancy, feeling sick or nauseated is quite common, as is vomiting. The degree of nausea and vomiting differs from woman to woman.

You may just feel a little sick in the morning and throw up once, or your may suffer from constant nausea and frequent vomiting throughout the day.

For most women, the nausea stops after the first three months of pregnancy. For a few, however, it is still a problem after four or five months.
