The present study investigates the association between stress levels and menstrual irregularities among 100 women aged 13-45 years in Sunehti Kharkhari village, Saharanpur. A questionnairebased cross-sectional survey was conducted, and data were analyzed using descriptive statistics and Chi-square test. The findings revealed that 48% of participants experienced menstrual irregularities, and stress levels were significantly associated with these disturbances (χ² = 18.72, p < 0.001; Cramer’s V = 0.433). High stress was strongly linked with irregular cycles, dysmenorrhea, and delayed menstruation, particularly among women aged 19–25 years. The study concludes that psychological stress plays a significant role in affecting menstrual health, highlighting the need for stress management and awareness programs to improve reproductive well-being.
