Once the egg leaves your ovary, it travels through one of your fallopian tubes toward your uterus. If pregnancy doesn't happen, your body doesn't need the thick lining in your uterus. Your lining breaks down, and the blood, nutrients, and tissue flow out of your body through your vagina. Voilà, it's your period!
