Your period should have come on the 6th, but it arrived on the 27th, and it's still not over.

Patient's question:

27th to come
3rd hasn't ended yet, usually it's around the 6th to come or black blood

Doctor's answer:

Irregular menstruation has many causes, which are typically classified into two major categories in clinical practice: one is functional, such as menstrual irregularities caused by endocrine dysfunction; the other is organic, such as conditions like pelvic inflammatory disease, endometritis, and endometriosis, which can also lead to menstrual irregularities.
Go to the hospital for a check-up and take medication accordingly. In the meantime, eat more foods that boost qi and blood, or try traditional Chinese medicine for regulating menstruation, such as angelica sinensis (Danggui), astragalus (Huangqi), and motherwort (Yimucao). Drink plenty of water, reduce spicy and irritating foods, pay attention to a balanced diet, and exercise more.
Wishing you good health.
