Frequently Asked Questions

How accurate are the period predictions?

Our tracker uses standard menstrual cycle calculations based on your input data. Predictions are estimates and actual cycles can vary due to stress, illness, lifestyle changes, and other factors. For best accuracy, update your last period date regularly.

What is the typical menstrual cycle length?

The average menstrual cycle is 28 days, but normal cycles can range from 21 to 45 days. Our tracker allows you to customize your cycle length to match your individual pattern for more accurate predictions.

How is ovulation calculated?

Ovulation is typically calculated as 14 days before your next expected period. This is based on the luteal phase being approximately 14 days long in most women, though individual variation exists.

What is the fertile window?

The fertile window includes the 5 days before ovulation plus the day of ovulation (6 days total). This accounts for sperm survival time and the egg's viability period.

Can I export my cycle data?

Yes! You can generate a comprehensive PDF report that includes your cycle information, predictions, phase explanations, and a visual 3-month calendar. This is useful for personal records or medical consultations.

Is my personal data stored anywhere?

No, all calculations are performed locally in your browser. No personal information is stored on our servers or transmitted anywhere, ensuring complete privacy of your menstrual cycle data.

What do the different colors mean in the calendar?

Red indicates menstrual days, yellow shows the follicular phase, light green represents the fertile window, dark green marks ovulation day, and light blue shows the luteal phase.

Should I consult a doctor about my cycle?

This tracker is for informational purposes only and should not replace medical advice. Consult a healthcare provider for irregular cycles, unusual symptoms, or any health concerns related to your menstrual cycle.
