Pregnancy is typically divided into three stages, known as trimesters. The first trimester spans from conception to 12 weeks, during which the embryo develops major organs and structures. The second trimester, from 13 to 26 weeks, involves significant growth, and the fetus becomes more active. The third trimester, from 27 weeks until birth, is characterized by further development and preparation for delivery.
