It is normal to have a small amount of bleeding on the seventh day of uterine cleansing. Generally, after the cleansing, the bleeding is about a week, and the longest is not more than two weeks, that is, a small amount of bleeding within two weeks belongs to the normal range. If there is still residue in the uterus, you can wait for menstruation if the residue is small, because sometimes menstrual blood can bring out the small residue. If there are more residues, it may be necessary to clean the uterus again. Do not touch cold water or brush your teeth with cold water for two weeks after the uterus is cleansed, and move properly every day to help the uterus recover and help the blood in the uterine cavity to drain out.
