Some women only have nausea in. the morning, and others have nausea all day. and night. Morning sickness typically begins. between 4 to 9 weeks of pregnancy and is. usually the most severe between 7 to 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!
