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.
Morning Sickness signified by feeling queasy, nauseous and actual vomiting is one of the least joyous aspects of being pregnant. In a survey of pregnant women the average start of morning sickness was 5.5 weeks after the last period. However 4-6 weeks is perfectly normal and for some ladies it might not happen until the hormones are significantly higher between weeks 8-12.
