If your period is one week early, if it is occasionally one week early, you can leave it alone and observe it temporarily. If your period is one week early twice or more, it may be caused by the decline of ovarian function. If you are older, it is physiological and can be left untreated for the time being. However, if a younger woman has frequent one-week early periods, it is recommended to have a hormone 6 test 2-4 days after the onset of menstruation to understand the function of the ovaries and whether the early periods are caused by early-onset ovarian function decline. If there are signs of ovarian decline, timely hormone supplementation therapy should be given to avoid early menopause due to further ovarian decline. This is because premature menopause in women can lead to menopausal syndrome and long-term complications, which are detrimental to women’s health.
