Morning sickness refers to the nausea and vomiting that some women have when they become pregnant. Morning sickness is very common in early pregnancy -- it affects more than half of all pregnant women.
Although morning sickness is more common in the morning, it can occur at any time of the day or night.
Morning sickness tends to go away later in pregnancy, and it's almost always gone by the second trimester (after 13 weeks, or during the fourth month). However, keep in mind that there isn't a set time for it to stop because each woman is different and each pregnancy is different.
