Morning sickness is a misnomer. For some pregnant women, the symptoms are worse in the morning and ease up over the course of the day, but they can strike at any time and, for many women, last all day long. The intensity of symptoms can also vary from woman to woman too. The medical term for morning sickness is nausea and vomiting of pregnancy. Up to three quarters of pregnant women have at least some nausea or vomiting during the first trimester, and about half have only vomiting.
