Doctor's answer:

There are many causes of natural miscarriage, including immunological factors, genetic factors, infectious factors, endocrine factors, anatomical factors, etc. In general, if a natural miscarriage occurs during the first pregnancy and the cause cannot be identified, it is unlikely to prevent future miscarriages through blind bed rest. Moreover, multiple miscarriages can cause significant harm to the body. Therefore, it is necessary to visit a hospital for a comprehensive examination to determine the cause of natural miscarriage and receive targeted treatment.
