Improper management of an impending miscarriage could potentially lead to an inevitable miscarriage. Therefore, it is crucial to rest during this period, preferably staying in bed. However, the specific duration of bed rest depends on the patient's clinical symptoms; for instance, if the woman experiences only minor vaginal bleeding and mild abdominal pain.

Typically, through timely conservative treatment for maintaining pregnancy, taking progesterone orally or receiving progesterone injections can quickly stop the bleeding and alleviate lower abdominal pain. Generally, the patient can get out of bed three days after the symptoms disappear, but if there is still significant bleeding, continued bed rest is necessary until the bleeding stops for one week.

(The use of medications should be conducted under the guidance of a doctor.)
