An endocrine test is also necessary when a period is pushed back. Menstruation is formed when the uterine lining peels off in response to cyclical changes in the ovaries, so delayed menstruation is related to abnormal ovarian function, so endocrine tests can be used to evaluate ovarian function and then determine the cause of menstruation postponement. To evaluate the basic endocrine function of women, it is important to note that the test should be performed on the 2nd to 4th day of the menstrual cycle on an empty stomach, and before the test, care should be taken to keep the mood calm and not to be too agitated so as not to affect the results of the test. For women with delayed menstruation, it is also necessary to be vigilant against the effects of mental stress, pregnancy and other factors, so it is necessary to go to the gynecology department of a regular hospital as soon as possible to improve the blood HCG, ultrasound, sex hormones and other related examinations, to clarify the cause of the disease and then under the guidance of the doctor to actively treat.
