After the vast majority of abortions, the contraction of the uterus takes about 3-4 days, and at the latest a week will return to normal, because after abortion there will be vaginal bleeding, and only if the uterus contracts the blood sinuses will close and the vaginal bleeding will stop. At the latest, vaginal bleeding after abortion should not exceed 7 days clinically, so the uterine contraction of the number of days the blood needs to be at the latest 7 days or so. If there is still vaginal bleeding for more than 7 days, it is important to go to the hospital for appropriate examination, which may be due to poor uterine recovery or due to the presence of intrauterine residuals, which may prolong the vaginal bleeding. In addition, after the abortion, if there is still blood in the vagina, you should not eat ginseng, deer antler, red dates and Colla Corii Asini, if you eat these will also cause the prolongation of vaginal bleeding.
