The main thing is to pay attention to rest and reduce activities during the process of fetal preservation, not to lie in bed for a long time without moving, which can easily affect the coagulation function of pregnant women and increase the risk of blood clots. During the period of fetal preservation, pregnant women should maintain a good state of mind, do not overstress, and at the same time can rest but do not stay in bed for a long time, try to avoid strenuous exercise and do not have intercourse. In addition to rest, we also need to use auxiliary fetal preservation drugs during the process of fetal preservation, and some patients with more serious symptoms need to be hospitalized for treatment.
