If a woman has not had her period for 15 days, she should first visit a gynecologist at a hospital to check the thickness of the uterine lining by ultrasound to see if there is any organic disease in the uterus, and also to check the blood HCG to determine if she is pregnant. Some women may mistake abnormal uterine bleeding due to pregnancy for menstrual flow. In addition, abnormal vaginal bleeding may also be due to endocrine disorders, which requires a sex hormone six test and a routine blood test to determine if there is any infection or anemia. For women with simple abnormal uterine bleeding, symptomatic treatment is needed to stop the bleeding, such as taking caffeic acid tablets and Plummer’s granules to stop the bleeding.
