This is general information, not medical advice.

What to log

  • Date and cycle day, from the first day of bleeding.
  • Physical: cramps, headaches, bloating, breast tenderness, sleep, energy.
  • Emotional: mood, irritability, anxiety, low mood.
  • Other factors: stress, exercise, alcohol, caffeine, medication.
  • Severity on a simple 0 to 3 scale so you can compare.

Spot the pattern

After two or three cycles, look for symptoms that repeat in the same window before bleeding and ease after it begins. If symptoms occur at random times, they may have other causes.

Things that may help

Many people find regular exercise, sleep, balanced meals and less caffeine and alcohol useful. Ask a clinician before using supplements or medication.

When to talk to a doctor

  • Symptoms disrupt work, study or relationships.
  • Mood changes are severe or you feel hopeless.
  • Pain is intense or new.

Bring your log. It makes the appointment far more useful. See how period trackers work and protect your data.
