ℹ️ About Safe Period Calculation

The safe period is a natural contraceptive method based on the menstrual cycle. It is most effective for women with regular cycles. This calculator provides an estimate only and should not be used as the sole method of contraception.

⚠️ Medical Disclaimer & Usage Tips

Please note: The Rhythm Method (Calendar Method) is not 100% effective (failure rate approx. 24%). This tool is designed for women with regular cycles (26-32 days). Stress, illness, and medication can alter your cycle. This tool does not protect against STIs. Always consult a healthcare professional before relying on natural family planning methods.
