Introduction
Pregnancy refers to the entire process starting from fertilization and ending with the expulsion of the fetus and its associated tissues from the maternal body. The gestational period is typically calculated from the first day of the last menstrual period, averaging about 280 days, or approximately 40 weeks. This process can be divided into three stages: early pregnancy, mid-pregnancy, and late pregnancy.
Generally, pregnancy refers to the process in which an embryo or fetus develops and grows inside the mother's body. A detailed explanation is as follows:
Pregnancy begins from fertilization and continues until the fetus and its associated tissues are expelled from the mother’s body. The gestational period is typically calculated from the first day of the last menstrual period and averages about 280 days, or approximately 40 weeks. This process can be divided into three stages: early pregnancy, mid-pregnancy, and late pregnancy. During early pregnancy, women may experience symptoms such as nausea, vomiting, and loss of appetite—commonly known as morning sickness. As the fetus develops, the pregnant woman’s abdomen gradually enlarges and her breasts begin to grow. As time progresses and the fetus matures, it will leave the mother’s body through either vaginal delivery or cesarean section, beginning independent life.
During pregnancy, women should pay special attention to nutrition, rest and exercise, regular prenatal checkups, and avoiding harmful substances to ensure both healthy fetal development and their own well-being.
