There are two main possibilities for a rise in blood chorionic gonadotropin after conservative treatment of ectopic pregnancy: the first one is that the drugs have not yet taken full effect. In general, after conservative treatment of ectopic pregnancy with mifepristone and methotrexate, blood chorionic gonadotropin is checked on the fourth and seventh day of treatment. In many patients, there is a mild increase in chorionic gonadotropin on the fourth day of treatment, mainly because the effect of the drug has not yet fully taken effect and the embryonic activity has not yet been completely killed, but there is still a small amount of activity. However, the rise in HCG in this case is usually not very high, but only a slight rise, which will all appear to fall on the seventh day. Secondly, if the blood chorionic gonadotropin is still rising on the seventh day, or if it rises very significantly on the fourth day of examination, this situation suggests that the treatment may have failed and the patient is not recommended to continue conservative treatment.
