During the occurrence of threatened miscarriage, it is generally necessary to rest in bed for a week. During this period, medication should be taken under the guidance of a doctor to preserve the pregnancy, and prenatal follow-up visits should be made at the hospital. There is abdominal pain or spotting during a miscarriage, but it has not yet progressed to the extent of miscarriage, so treatment to preserve the pregnancy can be administered. Additionally, emotional stability should be maintained during pregnancy preservation, avoiding stimulating the patient, ensuring rest, enhancing nutrition, and maintaining genital hygiene. Furthermore, during the pregnancy preservation period, one should rest in bed as much as possible and avoid activity.
