Signs and symptoms may include vomiting several times a day and feeling faint. It is more severe than morning sickness. Symptoms usually get better after the 20th week of pregnancy, but may last the entire pregnancy. The condition is also seen in patients with a hydatidiform mole and in multiple gestations.
