Morning sickness is a very normal thing for expectant mothers, but different women\’s reactions during pregnancy are actually very different. Some pregnant women have mild pregnancy reactions and may not even feel any obvious symptoms, but some pregnant women may have stronger pregnancy reactions and vomit whatever they eat.

In fact, the fetus grows slowly in the first trimester and does not need to be too much.
