You don't need to download anything to understand your cycle. You need to write four things down for three months. That's it.
What to track
Each day, write four entries in a notebook or notes app:
- The date. Obvious but essential. Pattern only shows up over time.
- Bleeding. None, spotting, light, medium, heavy. Day of cycle (day 1 is the first day of full bleeding).
- Mood, energy, sleep. One word for each. Calm, tired, broken. Whatever's honest.
- One symptom, the worst one. Cramps, headache, breast tenderness, breakout, bloat, brain fog. The standout for the day.
What you'll learn
After one cycle, almost nothing. After three, almost everything.
You'll spot which days of the cycle your worst symptoms cluster on. You'll notice if your luteal phase is getting longer or shorter. You'll see if your mood dips are tracking the calendar or your week at work.
If you take a supplement or change a habit, you'll have a baseline to compare against. That's the whole point.
The four phases
For context, here's roughly what the four phases look like.
- Menstrual (days 1 to 5). Energy low, prostaglandins high, cramps and fatigue.
- Follicular (days 6 to 14). Energy climbing, skin clearer, mood lifts.
- Ovulation (days 14 to 16). Peak energy and confidence for most women.
- Luteal (days 17 to 28). Slow descent, PMS sets in toward the end.
Yours might not look exactly like this. That's why you track.
Why not an app
Apps are fine. They also sell your reproductive data. If that doesn't bother you, use one. If it does, a notebook works the same and stays in your kitchen drawer.
