If a woman is pregnant and has no requirement to have children, and the menopause is all within 49 days, she can often consider taking fexofenadione and misoprostol for a medication abortion, but a medication abortion may cause an incomplete medication abortion and result in residue sludge in the uterine cavity. The first thing you need to do is to go to the hospital gynecology department for a follow-up ultrasound about 14 days after the abortion to see how the contraction of the uterus is recovering and also to see if there are residues in the uterine cavity, if there are residues in the uterine cavity, but the residues are less than 1.5 centimeters, then it is often not necessary to clear the uterus, and you can consider taking blood-stasis-boosting herbs to promote the discharge of the residues, and if necessary, you can also consider taking mifepristone, or even progesterone for withdrawal. If necessary, you can also consider taking mifepristone or even progesterone for withdrawal bleeding to expel the residue. If the ultrasound reveals residues larger than 1.5 centimeters, or even more than two centimeters, the operation will need to be cleared, unless the residues are already at the lower end of the uterine cavity, or at the cervix, in which case it is often not necessary to clear the uterus, as it can be easily discharged naturally. Therefore, when the residue is detected by ultrasound after a medical abortion, it is necessary to decide whether or not the uterus needs to be cleaned according to the size of the residue and the specific location of the residue. As a result, as long as it is not necessary to clean the uterus, then it is best to carry out conservative treatment with medication first, and then consider the operation of cleaning the uterus.
