Pregnancy

Pregnancy is the condition of carrying a developing embryo or fetus within the female reproductive system. It typically occurs after fertilization of an egg by sperm, leading to implantation in the uterine lining. The gestational period for humans usually lasts about 40 weeks, counted from the first day of the last menstrual period. During pregnancy, the body undergoes various physical and hormonal changes to support the growth and development of the fetus. These changes can affect many bodily systems and often result in a range of symptoms. The stages of pregnancy are generally divided into three trimesters, each characterized by specific developmental milestones for the fetus and different experiences for the pregnant individual. Pregnancy is a significant stage in human reproduction, culminating in childbirth or delivery when the baby is born. It can also be associated with various health considerations and requires proper prenatal care to ensure the health of both the mother and the child.
