Expecting women are recommended to take optimum rest during pregnancy, especially in the first trimester. It is because the body during this time undergoes several changes that may make the mother feel tired (21). Chronic fatigue can affect your and your baby’s health. Dr. Langdon recommends, “Pregnant women who have exacerbated signs and symptoms in the first trimester, such as morning sickness, dizziness, or any type of vaginal bleeding, should be on bed rest.”
