When to expect nausea during pregnancy. Nausea typically starts within four to eight weeks of gestation and is expected to subside between 13 and 14 weeks. However, it can start earlier and can last longer. Also, not every woman will experience nausea the entire duration of the first trimester. It could last only a couple of weeks or come and go throughout the first few months. Many refer to nausea during pregnancy as morning sickness, leading women to believe they will only experience nausea in the mornings. In fact, research shows that “morning sickness” actually occurs more often throughout the entire day, rather than just in the early hours.

I've had women who freaked out because they didn't get morning sickness, because they thought they were at higher risk of having a miscarriage, Dr. Francis says. But if you don't have morning sickness, it doesn't mean that you have abnormal hormone levels; it just means that you tolerate [pregnancy] better.. But don't get too complacent! Even if you're out of your first trimester, you may not be out of the woods. Although most women get their morning sickness between weeks 8 and 14, every woman and every pregnancy is different, and you may find that you develop pregnancy-related sickness later.

It's usually mild and goes away about midway through your pregnancy.
