2. Irregular Periods
Menstruation occurs approximately once every 30 days. It is not a precisely regular occurrence and it can be out by a few days or so each month, but every 30 days is still the general rule. Women will also usually know that their period is approaching because they begin to experience certain associated symptoms. One symptom of polycystic ovary syndrome is that the patients periods will become far more irregular. They can become very early or very late and, in some instances, their period might not even come at all. This occurs because of an imbalance in hormones that would otherwise cause regular menstruation.
