when does morning sickness start

Morning sickness typically starts around the sixth week of pregnancy, often about two weeks after a missed period. Most women begin to experience symptoms between the 4th and 7th week, with nausea peaking around weeks 8 to 11. The symptoms usually improve or go away by the end of the first trimester, around the 13th to 14th week, though some women may experience it into the second trimester or even throughout the entire pregnancy in rare cases. Despite its name, morning sickness can happen any time of the day, not just in the morning.
