Understanding Menstrual Cycles

The menstrual cycle is a natural process that occurs in people with uteruses, typically starting in adolescence and continuing until menopause. A normal cycle ranges from 21 to 35 days, with the average being 28 days. The cycle is counted from the first day of one period to the first day of the next period.

According to the American College of Obstetricians and Gynecologists (ACOG), a normal menstrual cycle consists of several phases: the menstrual phase (period), the follicular phase, ovulation, and the luteal phase. Understanding your cycle length helps you predict when your next period will arrive and plan accordingly.

Why Tracking Your Period Matters

There's something empowering about knowing exactly how many days until my next period. For health-conscious individuals, period tracking helps identify patterns, predict symptoms, and plan activities. For those trying to conceive or avoid pregnancy, tracking your cycle is essential for understanding your fertility window.

Studies show that people who track their menstrual cycles are more aware of their reproductive health and better able to identify irregularities or concerns. According to the Centers for Disease Control and Prevention (CDC), tracking your period can help you recognize patterns, identify potential health issues, and communicate more effectively with healthcare providers about your reproductive health.

The American College of Obstetricians and Gynecologists reports that menstrual cycles can vary significantly from person to person and even month to month. Factors such as stress, exercise, diet, weight changes, and medical conditions can all affect cycle length and regularity. Tracking your period helps you identify what's normal for your body.
