If you are 46 years old and don’t have your period, you need to see a gynecologist or endocrinologist in the hospital. The first thing to consider when a 46-year-old woman is not having her period is pregnancy. You can go to the gynecology department of the hospital for a urine pregnancy test or blood test to determine whether you are pregnant or not, and if the test confirms that you are pregnant, you will need to go to the obstetrics department of the hospital to do the relevant pregnancy tests. If there is no pregnancy, the lack of menstruation may be related to perimenopausal menstrual irregularities. After 40 years of age, the ovarian function gradually declines and the level of estrogen in the body decreases, resulting in irregular menstruation. The first thing you need to do is to take a blood test for sex hormone 6 to find out if you are approaching menopause, and if you are experiencing perimenopausal menstrual disorders, you can take medication to regulate your menstrual cycle under the guidance of your doctor. If the examination of hormone six is not yet menopausal, the lack of menstruation may be related to fatigue, environmental changes or medication, organic lesions, etc., need to be combined with ultrasound and sex hormone six examination, to exclude organic lesions can be given medication to regulate menstruation treatment.
