what are causes for a late period

Use a home pregnancy test as the first step to finding out whether you are pregnant. If you are not pregnant, other causes of missed or irregular periods include: Excessive weight loss or gain. Although low body weight is a common cause of missed or irregular periods, obesity also can cause menstrual problems. Eating disorders, such as anorexia or bulimia.
