Morning sickness usually begins during the first month of pregnancy
and continues until the 14th to 16th week. Although, some women can
have nausea and vomiting through their entire pregnancy. Morning
sickness is very common and does not hurt the baby in any way.The
exact cause of morning sickness is unknown. However, it may be
caused by either hormonal changes or lower blood sugar during early
pregnancy. Emotional stress, traveling, or some foods can aggravate
the problem.
