Irregular periods. Irregular periods are one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections, hormonal changes, endometrial and cervical polyps, fibroids, weight changes and others are a few common causes. Keep the appointment you scheduled to begin the evaluation.
