Threatened miscarriage, as the name suggests, is a precursor to miscarriage, typically manifesting in several ways: first, a feeling of heaviness or pain in the lower abdomen; second, vaginal bleeding. The presence of these two symptoms often indicates signs of a miscarriage. Regarding the management of threatened miscarriage, whether to proceed with treatment to preserve the pregnancy primarily depends on the severity of the condition and the value of preserving the pregnancy. First, for minor cases of threatened miscarriage, if there is only slight bleeding and mild abdominal pain, medication can be used to inhibit uterine contractions and reduce bleeding. Second, if there is significant vaginal bleeding and severe abdominal pain, and if the embryo has already been confirmed to have ceased developing, preserving the pregnancy is generally not recommended. It is advised to terminate the pregnancy promptly or let it proceed naturally. (Medication should be used under the guidance of a doctor.)
