Poor uterine regeneration: If the ultrasound examination is poor uterine regeneration, you need to use some drugs to promote uterine contraction under the guidance of the doctor, for example, you can intravenously inject hysteronin, and of course, you can also intramuscular injection of hysteronin. Appropriate use of antibiotics, because the bleeding continues for a long time, the chance of infection will increase. 2.
