Irregular cycles can make tracking menstruation and ovulation challenging, but the app is adapted for such cases. If you have an irregular cycle, you can still enter your menstruation start and end dates. The app will adjust its predictions based on this data, though the accuracy may be lower compared to regular cycles.

If you notice that your cycles vary significantly, consider keeping additional notes on your symptoms (such as mood changes or basal body temperature). These data points can help the app better understand the unique characteristics of your cycle and provide more accurate predictions for events like ovulation and fertile days.

It’s also important to remember that persistent cycle irregularity may signal the need to consult a doctor. Use the app as a tool for monitoring and discussing your health with medical professionals.
