This method is usually more effective for women who are less than 7 weeks pregnant. During a medical abortion, the doctor will check if the sac has been discharged, if there are any hairs visible, and if it matches the size of the gestational week. If it does, the bleeding will slowly decrease. If the bleeding is low or if there is a lot of bleeding, it does not mean that the bleeding is clean or that the bleeding is not clean, it depends on the individual. The main purpose is to see if there is any residue in the uterus, and if there is residue, the uterus should be cleared in time, so it is not suspected that the bleeding is not clean after the medical abortion, but the final confirmation of cleanliness should be known only through the re-examination of ultrasound.
