If the menstrual flow is low and does not flow out, you should have a checkup to see the specific cause, and then have a targeted treatment. If the low estrogen level and thinness of the uterine lining are the cause of low menstrual flow, you can use Jia Le under the guidance of the doctor, and choose the Chinese medicine to regulate menstruation and promote pregnancy pills or Ding Kun Dan for treatment. If you have had an abortion in the past, and have a low menstrual flow, accompanied by severe abdominal pain, you need to check the cervix to rule out whether there are cervical adhesions. If there are cervical adhesions, you can use a dilator to dilate the opening of the cervix, so that the menstrual blood that collects in the uterine cavity can be discharged smoothly. If there are adhesions in the uterine cavity, the symptoms of scanty menstrual flow are also likely to occur. It is necessary to break down the adhesions under hysteroscopy, and then apply medication to prevent adhesions.
