It is normal for adolescent women to stop menstruating when their reproductive organs are immature, and no special intervention is needed if the period does not last more than six months. If a woman of childbearing age has stopped menstruating: firstly, it is recommended to carry out a test for early pregnancy, if it is caused by early pregnancy, no special treatment is needed. Secondly, if early pregnancy is ruled out, it is recommended to take progesterone capsules or intramuscular progesterone injection orally, and the menstrual flow will appear around 3-7 days after stopping for 3 days in a row. If women of childbearing age have menstrual stoppage without timely treatment, it will easily affect normal conception. If a perimenopausal woman has stopped menstruation, it may be menopause, if the age is between 45-55 years old, it means that she has reached the age of menopause, if there are no uncomfortable symptoms, there is no need for special intervention.
