Pregnancy

Pregnancy is the physiological condition in which a female carries a developing embryo or fetus within her uterus. It typically begins with the fertilization of an egg by sperm, leading to the implantation of the fertilized egg in the uterine lining. Pregnancy is divided into three trimesters, each lasting approximately three months, during which significant physical and hormonal changes occur in the woman’s body to support the growth and development of the fetus. The average human pregnancy lasts about 40 weeks from the first day of the last menstrual period to childbirth. Pregnancy involves various stages, including conception, embryonic development, and fetal growth, and is a critical period for the health and well-being of both the mother and the child. It is characterized by a range of symptoms and complications, and prenatal care is essential for ensuring a healthy pregnancy and preparing for labor and delivery.
