If your period is not normal, first of all, it is recommended to do two examinations. 1. first, do a gynecological ultrasound examination to see if there are abnormalities in the uterine adnexa and endometrium, whether there are fibroids, ovarian cysts, ovarian tumors, or whether there are problems with the endometrium. 2. If the gynecological ultrasound examination is normal and the period is not normal, endocrine disorders are the most likely cause, so blood can be drawn to check the six female hormone levels to see if there are problems with estrogen and progesterone, and if the ratio of follicle stimulating hormone or luteinizing hormone is abnormal, resulting in abnormal periods. Depending on the test results, medication can be used to regulate the condition. The regulation of endocrine disorders, if used with western medicine, is usually with estrogen and progesterone regulation, or oral short-acting contraceptives. Chinese medicine is usually used to regulate menstruation and promote pregnancy pill, Wuji Baifeng pill, and menstruation and blood circulation capsule, etc.
