How can one confirm whether the embryo has been completely expelled after a medical abortion?

To confirm whether the embryo has been expelled after a medical abortion, clinical symptoms and ultrasound examinations can be used. In most cases, the gestational sac is discharged on the third day of medication. Women may experience intermittent abdominal pain, vaginal bleeding, and cervical dilation. An ultrasound can clearly show a well-defined endometrial line and no abnormalities within the uterine cavity, indicating that the embryo has likely been expelled. Ultrasound examinations should be performed at a正规 medical facility, with the following specific procedure:

1. Ten minutes before the examination, the patient should empty her bowels and bladder. She then enters the examination room and assumes the lithotomy position, exposing the area to be examined.

2. The doctor covers the ultrasound probe with a protective sheath and applies coupling gel, then positions it at the vaginal opening.

3. The probe is gently inserted through the vaginal opening, carefully advanced along the vaginal wall to the vaginal fornix, approaching the uterus, fallopian tubes, and ovaries. The probe is rotated inside the uterus to perform a comprehensive, multi-angle examination.

4. In cases where the embryo has been successfully expelled, the ultrasound will show a clear endometrial line and no abnormal findings within the uterine cavity.

Medical abortions must be conducted at正规 hospitals; self-administering medications at home without supervision can lead to serious complications such as severe hemorrhage. After the embryo is expelled, women may take prescribed oral medications to promote uterine contractions and help expel retained blood clots from the uterine cavity. If heavy bleeding occurs after a medical abortion, prompt surgical intervention is necessary.
