Tracking your menstrual cycle is important as it allows you to identify irregularities when they appear. Though these irregularities are not always serious, understanding what’s normal for your body is always a good idea as it allows you to know where you are in your monthly cycle at any given time.
The average menstrual cycle ranges from 21-35 days. That said, up to 25% of women have cycles that are shorter or longer than this, or experience issues with flow, cramping, and more.
