More than half of pregnant women have nausea and vomiting, especially during the first trimester. Despite its name, you can have morning sickness any time of day. It doesn't mean your baby is sick, and it doesn't hurt you or your baby. Pregnancynausea is probably caused by the sudden increase of hormones in your body. It's usually mild and goes away about midway through your pregnancy. Some women never feel nauseous during their pregnancy.
Call Doctor If:
You have flu-like symptoms, which may be a sign of illness.
You feel dizzy or lethargic.
You have severe vomiting constantly or several times a day.
