Pregnancy usually lasts for 40 weeks or nine months. Pregnancy is divided into three trimesters. The first trimester is the being of the
embryo developing in the early stages of the mother’s uterus, which is the developing form of the placenta or umbilical
cord. The second trimester is when the embryo changes or grows into a fetus and starts to develop all its human parts and
it’s body system (nervous, muscular, and circulatory). The third trimester is the complete development of the fetus
and is capable to live outside the mother’s womb.
