It is not easy to terminate an unwanted pregnancy beyond 70 days, and in principle, the earlier the better, because beyond 70 days it is not possible to perform an abortion directly, and it is necessary to be hospitalized for induced abortion. Symptoms are relatively more severe, and the patient experiences more pain as well as bleeding for a longer period of time, which is more damaging to the patient. Once an unwanted pregnancy is detected and the ultrasound examination confirms an intrauterine pregnancy, in principle, the earlier the termination of pregnancy is carried out, the less damage it will cause to the woman. Within 49 days, medication abortion can be considered, and above 49 days, abortion can be performed directly. Induced abortion can only be performed if the pregnancy is within 70 days of termination and the diameter of the gestational sac is at least 1cm. After the termination of pregnancy, if there is no desire to have children in the short term, it is recommended to use strict contraception.
