Regardless of whether you are having an abortion or a medication abortion, if the residue in the uterine cavity is 2.6cm x 1.5cm, it means that the residue is relatively large. This kind of residue needs to be cleared, otherwise it will cause infection in the uterine cavity or irregular vaginal bleeding, and sometimes there will be heavy bleeding, so it is necessary to do the procedure of clearing the uterus as soon as possible. If the residue is within 1cm and there is no vaginal bleeding, it can be observed, or anti-inflammatory drugs can be applied, and drugs promoting uterine contraction and drugs promoting blood circulation and removing blood stasis can be taken orally at the time of the next menstrual period. When the menstrual period is clean and then review, most people will be able to expel the residue with the menstrual blood, if there is still residue after the menstrual period is clean, it is still necessary to clear the uterus for treatment.
