After taking birth control pills, I've been bleeding for several days.

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 properly regulate blood circulation, causing blood to overflow outside the vessels. Alternatively, it may be due to chronic blood loss, where qi is consumed along with the blood, eventually leading to qi deficiency that cannot hold the blood. It is recommended to use a large dose of astragalus root decoction to invigorate qi and stop bleeding.
