What are the symptoms of PCOD affecting menstruation?

The symptoms of PCOD can show its effect in various ways, that includes: irregular periods, absence of periods, heavy menstrual bleeding, and painful periods. Periods that are less frequent have less than eight per year, with cycles longer than 35 days. Absence of periods lasts for three months or longer, and irregular periods vary significantly in duration, making it difficult to predict when the next period will occur.
