Menstruation is a unique physiological characteristic of women. Periodic menstrual flow is regulated by the brain, ovaries and uterus. Therefore, irregular menstruation can occur when there is a problem with one of these components. Excessive fear of pregnancy can cause emotional stress in patients. This can lead to a short period of brain dysfunction and delayed menstruation. When this occurs, there is no need to worry too much. Patients are advised to relax and relieve stress to promote normal brain function. If you are unable to relieve stress on your own, you can try to divert your attention to avoid being overly focused on the issue of pregnancy. After relaxing, pay attention to observe whether menstruation comes normally. Most patients can resume their normal menstrual cycle after relaxing. If your period is still coming, you should consult your local hospital for hormone tests to rule out endocrine disorders that may cause delayed menstruation. If hormone levels are abnormal, medication to regulate menstruation may be necessary. It is recommended that women of childbearing age who are concerned about pregnancy should use good contraceptive measures, tools and medications to avoid psychological and physical damage due to unwanted pregnancy. Excessive psychological stress may cause irregularity of menstruation. Therefore, adjusting your mood and relaxing your stress is what needs to be a concern for all women.
