You can’t have an abortion on the 30th day of pregnancy, whether it’s a medical abortion or an abortion. At this time, because the time is too short, the gestational sac cannot be seen during the ultrasound, so if the gestational sac cannot be seen, ectopic pregnancy cannot be ruled out, and there is a risk of missed suction or danger during the abortion. If you want to have a medical abortion, you must see the gestational sac in the uterine cavity during the vaginal ultrasound after 35 days; if you want to have an abortion, you must see the gestational sac more than 1.0 cm during the abdominal ultrasound after 40 days of pregnancy before you can have an abortion. Therefore, if you want to terminate the pregnancy, you must see the gestational sac in the uterine cavity after the ultrasound before you can have an abortion.
