A typical cycle lasts between 21 and 35 days, but anything between 25 and 35 days is generally considered normal.

  • Follicular phase: This phase starts on the first day of your period and ends with ovulation. During this time, follicles (tiny sacs in your ovaries) mature, each containing an egg. The lining of your uterus (endometrium) also thickens in preparation for a potential pregnancy.
  • Ovulation: This is the release of a mature egg from an ovary. It typically occurs around day 14 of a 28-day cycle, but it can vary.
  • Luteal phase: This phase begins after ovulation and lasts about 14 days regardless of cycle length. The corpus luteum (a structure formed from the empty follicle) produces progesterone, a hormone that helps prepare the lining of your uterus for the implantation of a fertilised egg. If pregnancy doesn't occur, the corpus luteum disintegrates, progesterone levels drop, and your period starts.

The most straightforward way to track your cycle is to mark the first day of your period on a calendar. This establishes your cycle's starting point. Continue marking the start of each subsequent period. After a few months (ideally 3-6 cycles), you can calculate your average cycle length by:

  • Adding the number of days in each of your recorded cycles.
  • Dividing the total number of days by the number of cycles tracked.

    • For example, if your periods arrived on days 1, 28, and 32 of a three-month period, your cycle lengths would be 27 days, 28 days, and 32 days, with an average cycle length of (27 + 28 + 32) / 3 = 29 days.

    Once you know your average cycle length, you can use it to:

    • Predict your period: By subtracting 14-17 days from the first day of your last period (assuming ovulation occurs around day 14), you can estimate when your next period might arrive.
    • Identify your fertile window: Ovulation typically occurs around day 14 of your cycle, but it can vary. Your fertile window encompasses the few days leading up to ovulation and the day of ovulation itself (generally considered to be 3 days before and 1 day after ovulation).

    Another effective way to calculate your menstrual cycle is to track it over several months. Here's a step-by-step approach:

  • Gather your supplies: You can use a period tracking app, a physical calendar, or simply a notebook.
  • Mark your period: On the first day of your period, mark it on your chosen tracking method.
  • Track daily: Note any physical changes you experience throughout your cycle, such as cervical mucus consistency, breast tenderness, or mood swings. These can be early signs of ovulation.
  • Identify ovulation (optional): While not essential for cycle calculation, some women like to pinpoint ovulation. There are various methods for this, including ovulation predictor kits, basal body temperature tracking (recording your morning temperature before getting out of bed), and observing cervical mucus changes.
  • Repeat for several months: The more cycles you track, the more accurate your understanding of your typical cycle length will be.

    • Cycle variability: It's normal for your cycle length to vary slightly from month to month. Stress, illness, travel, and certain medications can all influence your cycle.
    • Irregular cycles: If your cycles consistently differ by more than 7 days or you experience frequent missed periods, consult a medical professional to rule out any underlying conditions.

    Tracking your menstrual cycle empowers you with valuable knowledge about your body. By following the steps outlined above, you can gain a deeper understanding of your cycle's unique rhythm and use this information to plan ahead, optimise your well-being, and make informed decisions about your health.
