During the month, blood builds up in the lining of your uterus, which will help a baby develop when you're older and want to have a family. It's a natural process, says Sharon Horesh Bergquist, MD, at the Emory School of Medicine in Atlanta.

Most of the time, a fertilized egg is not implanted in your uterus, and the blood sheds out of your body during your monthly period.
