HCG is human chorionic gonadotropin, which is above 100 mIU/ml on the 30th day of pregnancy, with individual variations. In normal early pregnancy, HCG rises by 70% or even double every other day, so the 30-day HCG should be at least 100 mIU/ml. If the HCG rise is low or almost non-existent in the early stages of pregnancy, it is necessary to exclude the possibility of ectopic pregnancy and embryonic arrest. Human chorionic gonadotropin is the hormone secreted by the placental villi, as each woman’s hormone levels are not the same after pregnancy, so the value of human chorionic gonadotropin varies individually, it is recommended to take regular pregnancy tests, and if it is lower than the normal value, you should actively cooperate with your doctor to carry out treatment.
