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.
I've never heard of a women getting morning sickness before 5 weeks pregnant, but most women don't start getting morning sickness between 6 and 8 weeks. Morning sickness depends on the person some get it early on some later. Some it only last for a little while, some have it their entire pregnancy. It can hit in the morning, afternoon, evening, and late night. I had it in the afternoons for about 2 weeks when I was around 16 weeks with my first and never had any with my second. Hoping the I don't have any with my third!
