Changing cycles

A period tracker for cycles that do not follow a script.

When your cycle timing changes, your history matters more than a perfect prediction. RedBird Period Tracker lets you keep a record of what actually happens.

A guide to your own experience

Record dates without judgment

Log the first day of each period and any other details you find helpful. Add symptoms, mood, sleep or energy on the days that matter to you. Over several cycles, your entries can provide a clearer picture of your own timing and experiences.

Treat forecasts as estimates

Cycle forecasting can be convenient, but no app can guarantee when your next period will start. Variability can make estimates less reliable. RedBird shows cycle context while allowing you to keep a record of real dates. Do not rely on a forecast for contraception or clinical decisions.

When to speak with a professional

Irregular timing can have many explanations. If a change is new, persistent or concerning, a clinician can help assess it. A dated record of bleeding and symptoms may help you describe the pattern. The NHS recommends keeping a symptom diary before seeking care for period problems. RedBird is not a diagnostic tool.

Common questions

Can RedBird predict an irregular period exactly?

No. Any forecast is an estimate, particularly when cycles vary.

Can I record symptoms between periods?
