An irregular periods, also known as an irregular menstrual cycle, occurs when your monthly menstrual cycle deviates from the typical 28-day pattern. While a cycle can normally range from 21 to 35 days, cycles outside this range—or cycles that vary significantly month to month—may be considered irregular.
Understanding the causes and treatments of irregular periods is essential for maintaining reproductive and overall health.
What Are Irregular Periods?
Irregular periods refer to variations in:

Birth control pills, fertility drugs, or other hormonal treatments can affect cycle regularity.
