After the clearance of the gravida, it is better to wait for two years before getting pregnant. After the gravid surgery, the HCG in the blood needs to be checked once a week. As long as it drops to normal within 3 months, it means that the possibility of benign gravidity is higher. Because there are infiltrative gravida, infiltrative gravida usually do not drop to normal within three months. The diagnosis of infiltrative staphyloma can also be made if the number of cases is rising even after the drop, or if there is no significant drop for three consecutive weeks. It is possible that the infiltrative staph may recur within two years after clearance, so it is safer to get pregnant after two years. If the HCG rises within three months, infiltrative staph is likely to be large and chemotherapy is needed.
