What problems are there when the menstrual period is long, with a large amount and dark color?

Patient's question:

Two years ago, after giving birth and completing the 40-day postpartum period, I have been experiencing irregular bleeding. My menstrual periods are long, with heavy flow and blood clots, and the blood is dark... I was treated at the Taiyuan Maternal and Child Health Hospital. The doctor said that during the postpartum period, my mood was not good, and my uterus did not recover well. I took several courses of traditional Chinese medicine

Doctor's answer:

Hello, considering irregular menstruation may be related to medication, endocrine disorders, and miscarriage, you can take Wuji Baifeng Pill or Chinese herbal medicine for regulation. If necessary, you may undergo an endocrine panel test and hormone-based artificial cycle therapy. For those with heavy bleeding, Gongxuening and Luoluo blood can be used for treatment. It is important to maintain local hygiene and avoid spicy and irritating foods.
