The term prenatal period refers to the time in pregnancy between conception and birth. The prenatal period last for 40 weeks, which is roughly nine months. The prenatal period is divided into three trimesters, with each trimester lasting approximately three months. During this time, the embryo develops into a fetus and then into a viable human baby. There are many changes in both mother and child during the prenatal period, including weight gain in both and physical and hormonal changes in each.
During the first trimester of the prenatal period, a woman goes through many physical and emotional changes. This period generally begins with a missed period, which leads to a positive pregnancy test. During the first trimester, the doctor will establish a due date for the baby and may perform an ultrasound to ensure proper fetal development. The soon-to-be mother will likely experience morning sickness and food cravings during the first trimester. Hormonal changes may cause mood changes such as crying easily or extreme euphoria.
Fetal development during the first trimester is remarkable. Conception occurs when a sperm cell and egg cell join. These cells grow and multiply immensely during the first few weeks of the prenatal period. By the end of the first trimester, key organs have begun to develop, including the brain, heart, and lungs.
The second portion of the prenatal period is referred to as the second trimester. The risk of miscarriage is greatly reduced by this point, and the uncomfortable symptoms of morning sickness generally fade away. At this point, the new mother may experience the urge to urinate more frequently because of pressure caused by the growing fetus. The pregnancy tends to become noticeable to others at this point, and maternity clothes are typically needed now. All of the important organs have already formed in the fetus, and this trimester focuses on further growth and development of these vital body systems.
The body systems of the fetus continue to mature in the third trimester. Early labor is possible at this point, and the chances of infant survival is high. Lung development increases dramatically during this time, and most body hair has disappeared.
