Understanding Your Menstrual Cycle: A Practical Guide
30 September 2026 · Global Women's Week
What's actually happening each phase of your cycle, and what's worth flagging to a doctor.
A typical menstrual cycle runs 21–35 days, and it's really four phases in one: menstrual, follicular, ovulation, and luteal. Each phase comes with its own hormone shifts — and those shifts explain a lot of the energy, mood, and appetite changes many women notice through the month.
Tracking your cycle for a few months (a notebook or any period-tracking app works) makes patterns visible: when you tend to have the most energy, when cravings hit, when mood dips are common. That awareness alone helps with planning demanding work or workouts around your natural rhythm rather than against it.
Irregular cycles aren't automatically a problem — stress, travel, and weight changes all shift timing. But cycles shorter than 21 days or longer than 35, periods lasting more than 7 days, or very heavy bleeding are worth a conversation with a doctor.
Quick tips
- Track cycle length for 3 months before assuming something is 'irregular'
- Iron-rich foods help offset losses during heavier periods
- Severe pain that disrupts daily life is not something to just 'push through' — it's worth investigating
