Rutumati Lakshan describes characteristic cognitive, physiological, and behavioural changes observed in women during this period. While clinical methods such as transvaginal ultrasonography and endometrial assessment provide accurate information on ovulation timing and estrogen status, they are time-consuming, costly, and operator-dependent. This study presents a questionnaire-based tool that collects information on symptoms and cycle patterns, translating classical Rutumati Lak?a?a into systematic, assessable parameters for evaluating the fertile window. The tool offers a non-invasive, cost-effective screening method for identifying the fertile period; however, it cannot precisely determine ovulation and requires further validation. This approach provides a foundation for fertility awareness, preconception counselling, and research, integrating Ayurvedic principles with modern reproductive monitoring.
