A calendar helps organize, not predict perfectly
Recording period dates, symptoms and changes in wellbeing makes it easier to review your personal history. A menstrual calendar can help you compare months and prepare useful information for a healthcare consultation.
Predictions are based on earlier records and assumptions about cycle length. They do not directly observe everything happening in your body. Treat an expected date as an approximation, not a guarantee.
Why cycles vary
Day one of a menstrual cycle is the first day of a period. The cycle continues until the day before the next period starts. Even with a fairly regular pattern, every month does not need to be identical.
Routine changes, stress, hormonal shifts and life stages can influence cycle patterns. The NHS explains that cycles can vary and advises seeking medical advice when your usual pattern changes or you have concerns.
Predictions are not contraception
A wellness calendar cannot establish exactly when ovulation occurred. Showing an estimated fertile window does not mean that other days are guaranteed to be free of pregnancy risk.
Do not use CicloAura predictions to prevent pregnancy or to make medical decisions. The NHS does not officially recommend fertility-tracking apps as contraception. Seek qualified advice if you need contraceptive or fertility guidance.
Context matters more than a perfect date
Notes on how you felt, symptoms and recurring patterns can be more useful than trying to force a calendar to match a predicted day. If you have missing information, leave it missing rather than making up entries.
