Medical Disclaimer

The content and calculator are educational only, not medical advice, diagnosis, or contraception guidance. Ovulation and period dates are estimates. Irregular cycles and individual variation affect predictions. No date is guaranteed safe for avoiding pregnancy. Calendar estimates cannot reliably confirm or exclude pregnancy risk. Seek qualified healthcare guidance for medical concerns.

Do not rely on this website alone for health or pregnancy decisions. It cannot determine whether you are pregnant. Content and calculations have not been independently reviewed by a medical professional; an automated review is not clinical validation.
