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.
Nausea and vomiting usually go away by 12 to 14 weeks of pregnancy. But in some cases, it can last well into a pregnancy. If you have severe, persistent nausea and vomiting or are unable to take in fluids, see your doctor or nurse-midwife right away.
