Although you do not look pregnant during your first trimester, your body is changing as it accommodates the fetus. In the first few weeks following conception, your hormone levels change, your uterus begins to support the growth of the placenta and the fetus, your body starts to make more blood to carry oxygen and nutrients to the fetus, and your heart rate increases. These changes in your body can cause fatigue, morning sickness, headaches, and dizziness. Learning how to relieve these normal symptoms of pregnancy, along with learning how to distinguish between the normal discomforts of pregnancy and signs of a problem, will help you throughout your pregnancy.
