If there is a decreasing trend of blood HCG in ectopic pregnancy without treatment, it is a benign result, which is good. Because the trend of decreasing blood HCG only occurs when the embryo of ectopic pregnancy stops developing, it is recommended to continue to observe the situation of blood HCG, for example, blood can be drawn and tested again every other day. If the blood HCG shows a continuous decrease, it indicates that the ectopic pregnancy sac has died or miscarried. To find out whether there is still pain in the lower abdomen, it is better to do another ultrasound examination to find out whether the original ectopic pregnancy mass has significantly shrunk or disappeared, and clinically combined with the blood HCG, it is possible to find out whether the ectopic pregnancy has improved.
