A small amount of bleeding three months after childbirth suggests that there may be uterine contractions and residual blood in the uterine cavity. It is recommended to go to the gynecology department for a gynecological ultrasound to see the condition of the uterus. If there is a small amount of blood in the uterine cavity, you can take certain oral blood-stasis-boosting drugs to help stop the bleeding. However, if the endometrium is normal and there is no abnormal hyperplasia or uneven echogenicity, certain anti-inflammatory and hemostatic drugs should be taken orally to help restore the uterus to normal so that prolonged bleeding will not affect your health. Observe whether there is still this situation in the next month. If this situation still exists, it is recommended to take blood tests for endocrine hormones to rule out any abnormalities in endocrine hormones, and according to the situation, artificial cycle regulation can be carried out to help the uterus return to normal.
