The discharge of a large clot of blood is generally abnormal. After childbirth, a mixture of blood, necrotic membranes and other tissues is discharged through the vagina as the uterine meconium and placenta are shed. If there is a large blood clot, you should pay attention to the possibility that the uterus is not fully recovered, or there may be residual placenta and fetal membranes in the uterine cavity.1. Retained embryonic tissue in the uterine cavity: If the blood clot contains rotten flesh-like tissue, it is caused by the detachment of retained embryonic tissue such as fetal membranes and placenta in the uterine cavity, and you must go to the hospital for examination. If there is a significant reduction in vaginal bleeding after a large clot is discharged, you can observe it temporarily and take some oral uterine contraction drugs such as motherwort granules or new biochemical granules as prescribed by the doctor, which are very beneficial to the discharge of malignant dew, and if necessary, you can consider surgery to clear the uterus; 2. Inadequate. Due to the lack of contraction of the uterus, the blood in the uterine cavity cannot be discharged in time, and a large amount of blood accumulates in the uterine cavity, forming a blood clot. In this case, you should consult a doctor at the first time and give ergometrine and uterine contraction under medical advice, and supplement with Chinese medicine treatment such as biochemical soup, motherwort and Chinese foot bath. If there is a combination of infection, abdominal pain may occur. You should promptly undergo pathogenic examination to clarify the germs and carry out anti-infection treatment.

Ensure sufficient sleep, pay attention to rest, strictly prohibit intercourse, change sanitary napkins regularly and keep your private parts hygienic. If the malodorous discharge persists or is accompanied by foul odor, or if there is fever, headache, lower abdominal cramps, or vaginal discharge of tissue, it is recommended to visit a hospital for necessary tests to exclude other diseases.
