The absence of menstruation despite not being pregnant may be caused by long-term sleep deprivation, excessive mental stress, or endocrine disorders. In addition, over-restricting food intake can also lead to delayed or absent periods. Furthermore, certain medical conditions such as polycystic ovary syndrome (PCOS) can result in the absence of menstruation even when pregnancy is ruled out. It is recommended to visit a hospital for further examination and appropriate treatment based on the underlying cause.
