Motion sickness is a normal response of the body to abnormal changes. The severity of motion sickness depends on various factors, including pregnancy. Some women may only experience motion sickness during pregnancy, while others who have had motion sickness before may find it worsens during pregnancy.

It has been observed that pregnant women are more prone to motion sickness. They often feel nauseous and vomit during travel. Some women only experience this during the pregnancy period, while for others, pre-existing motion sickness worsens during this time.
