The Vietnamese word "hành kinh" refers to the process of menstruation, which is a natural biological cycle that occurs in women. It is the monthly shedding of the uterine lining when pregnancy does not happen.
Hành kinh đều: This means "to menstruate regularly."
Hành kinh không đều: This means "to have irregular menstruation."
While "hành kinh" primarily refers to menstruation, it can also be used in broader discussions about women's health and reproductive rights. It does not have significant alternate meanings outside of this context.
In summary, "hành kinh" is a crucial term in discussing women's health and menstrual cycles.
