Breast tenderness and delayed menstruation are not necessarily pregnancy. Generally speaking, if menstruation is delayed for more than a week, pregnancy should be ruled out first. If pregnancy is ruled out, this situation is mainly considered to be a woman’s endocrine dysfunction caused by menstrual disease. First of all, it is necessary to exclude all kinds of organic causes, and it is recommended to go to the gynecology department to improve the relevant examination, such as the ultrasound of the uterus and ovaries and sex hormone examination. If there is no abnormality, we should pay attention to daily life management, such as controlling emotions, relieving stress, combining work and rest, eating less hormone-containing and stimulating foods, eating more seasonal fruits and vegetables, and exercising moderately.
