Vaginal bleeding stops a few days after the abortion and then occurs again, commonly due to the following reasons: First, vaginal bleeding occurs again due to lack of attention to diet, such as eating too much ginseng, deer antler, jujube, gelatin and other foods or drinking alcohol, it will bleed again. Secondly, fatigue due to poor rest causes vaginal bleeding again. Thirdly, due to the infection in the uterus, it will be accompanied by pain in the lower abdomen or the odor of vaginal secretion, which needs anti-inflammatory treatment. Therefore, for the situation that vaginal bleeding stops after abortion and then occurs again, it is recommended to do ultrasound examination to find out whether the uterus recovers normally, whether there is accumulation of blood in the uterine cavity, and whether there is any residual tissue.
