If the subchorionic hemorrhage occurs in the early stage of pregnancy, the bleeding volume is small and the embryo can continue to grow and develop after bed rest and fetal preservation treatment, so it can be observed and treated, and regular obstetric checkups can be performed later. Therefore, in cases of subchorionic hemorrhage after pregnancy, bed rest, anti-blood and anti-infection medication, and fetal preservation medication should be given to ensure that the fetus receives adequate nutrition for growth and development. If subchorionic hemorrhage occurs after pregnancy, it is also important to maintain a regular lifestyle and not to be overly stressed in order to preserve the pregnancy.
