What are the reasons for a small amount of bleeding in the middle of the menstrual cycle?

Patient's question:

No

Doctor's answer:

In your case, the bleeding may be caused by qi deficiency failing to control blood, often resulting from prolonged illness, exhaustion, or spleen deficiency leading to qi deficiency. When qi is deficient, it cannot regulate the circulation of blood, causing blood to overflow outside the vessels. Alternatively, chronic blood loss may deplete qi, turning it into qi deficiency that fails to hold the blood. It is recommended to take a large dose of Astragalus root decoction to replenish qi and stop bleeding.
