When threatened miscarriage occurs, attempts are generally made to carry out treatment to save the pregnancy. Whether the treatment can successfully save the pregnancy mainly depends on the severity of the symptoms, whether the treatment is timely, and the quality of the embryo itself.

Firstly, if it is a mild threatened miscarriage, such as mild lower abdominal pain or light vaginal bleeding, in most cases, the pregnancy can be saved; if the symptoms are very severe, with heavy vaginal bleeding and intense abdominal pain, sometimes the pregnancy may not be saved.

Secondly, when threatened miscarriage occurs, treatment should be selected based on the cause, including rest and medication. If the treatment is not timely, the pregnancy may not be saved.

Thirdly, if the quality of the gestational sac is good, then even if a mild threatened miscarriage occurs, the pregnancy can often be saved; however, if the quality of the gestational sac is poor, then even with medication treatment, the pregnancy often cannot be saved.
