Sickness and Vomiting in Pregnancy
Many pregnant women feel sick or vomit during early pregnancy. In most cases it is mild and does not need any specific treatment. In more severe cases, an anti-sickness medicine is sometimes used. Low body fluid (dehydration) is a complication in severe cases. See a doctor if you suspect that you are becoming dehydrated.
