The abortion milk is dark red and the amount is relatively small, often much less than the amount of menstruation, and the bleeding time does not exceed one week in most cases. If the color of the milk is purulent or smelly, it may be an infection, often accompanied by pain in the lower abdomen, and it is recommended to go to the hospital for appropriate examination and treatment. If the vaginal bleeding lasts for more than a week, it is most likely due to poor uterine regeneration or intrauterine residue. It is recommended to go to the hospital for an ultrasound examination to find out the size of the uterus and whether there are residues in the uterine cavity.
