Why prediction of my ovulation and fertile window moves?Updated 6 months ago

Mira App’s predictions are based on your cycle information and historical data. The more results Mira App gets from your Mira Monitor, the more accurate the predictions become. Sometimes the hormones behave differently than expected and the LH peak does not occur on the day of the predicted peak. In this case, Mira App will move the predicted date until it catches the LH peak.
