After a medical abortion, the uterus takes about 20-30 days to close, and most women have their uterine opening completely closed after one normal period. The abortion will be followed by prolonged bleeding and the cervical os is open during the bleeding process, and the oral mifepristone and misoprostol tablets will soften the cervix and open the cervical canal including the cervical os, which will facilitate the discharge of the gestational sac and endometrial blood in the uterine cavity and restore the normal uterine cavity shape. After 1 month, you can go to the hospital for a follow-up ultrasound to ensure that the cavity is normal. Some women with prolonged bleeding for more than 10 days should go to the hospital for a timely review to avoid residual tissue in the uterine cavity, which may affect their reproductive health in the future.
