Morning Sickness

What is morning sickness?

Morning sickness is the nausea and vomiting that some women have when they become pregnant. It is caused by the sudden increase in hormones during pregnancy. Although morning sickness is more common in the morning, it can last all day for some women.

How long will morning sickness last?

Morning sickness is very common early in a pregnancy. It tends to go away later in pregnancy, and it's almost always gone by the second trimester (the fourth month). But there isn't a set time to say it will stop because each woman is different, and each pregnancy is different.

Will morning sickness hurt my baby?

It shouldn't. Morning sickness can become more of a problem if you can't keep any foods or fluids down and begin to lose a lot of weight. Many doctors think morning sickness is a good sign because it means the afterbirth (the placenta and fetal membranes) is developing well.
