The Emergency Contraception Calculator is a helpful tool designed to assess the potential risk of pregnancy based on specific factors surrounding unprotected sexual encounters. By inputting various details related to the timing of unprotected sex, menstrual cycle regularity, days since the last period, and previous emergency contraception usage, the calculator generates a risk score. This score reflects the likelihood of a pregnancy occurring after unprotected intercourse.
