Video Summary

Pregnancy is the time in a woman's life when she is carrying a fetus in her uterus. The average pregnancy lasts for 40 weeks. During this time, the fetus develops from a single cell to a fully formed baby. The pregnant woman's body undergoes many changes to accommodate the growing fetus. These changes include weight gain, changes in the shape of the woman's body, and hormonal changes. Pregnancy can be a time of joy and anticipation, but it can also be a time of challenges. Women who are pregnant should take care of themselves by eating a healthy diet, getting regular exercise, and following their doctor's recommendations.
