The document provides information about pregnancy and fetal development from fertilization through the first, second, and third trimesters. It describes how the embryo implants in the uterus and develops organs and limbs over the course of weeks. The placenta and umbilical cord form to support the growth of the fetus and allow nutrient exchange with the mother. The fetus' movements begin at 9 weeks and its sex may be apparent at 11 weeks.
