Sometimes predictions may be inaccurate, especially if your cycle data was entered incorrectly or hasn’t been updated for a long time. The first step in this case is to check all the entered information. Ensure that the dates of your last menstruation are correct, and your cycle length is accurate.

If the data is correct but predictions are still off, the issue may stem from irregular cycles. In such cases, the algorithm may struggle to provide precise predictions. Try adding additional information, such as symptoms, to help the app better understand the nuances of your cycle.

For those with irregular cycles, it’s also recommended to consult a healthcare professional, as significant changes could indicate hormonal or physiological issues.
