How common is morning sickness? During early pregnancy, nausea, vomiting and tiredness are common symptoms. Around half of all pregnant women experience vomiting, and more than 80% of women (80 out of 100) experience nausea in the first 12 weeks.
Some women have more severe symptoms and have frequent and/or longer bouts of vomiting. You may just have nausea and no vomiting. Sickness and vomiting usually start before the 9th week of pregnancy. In 9 out of 10 women, the symptoms have gone by 16 weeks of pregnancy. However, some pregnant women have some sickness throughout all of their pregnancy. Sickness and vomiting in pregnancy can be a difficult problem to cope with.
