Menstrual irregularities (including missed periods) can occur for a number of different reasons. Pregnancy is just one possibility. Irregular periods can be caused by hormonal imbalances, perimenopause, illness or infection, use of certain medications, and other more serious conditions. Women who are dieting or exercising excessively may also skip periods. In addition, increased stress levels and changes in routine may affect the regularity of menstrual cycles. If you have skipped more than one period andyou are not using a progestin-only method of birth control, you should probably be evaluated by a medical professional to determine the cause.
