The normal value of human chorionic villus count in early pregnancy is not easy to determine, normally human chorionic gonadotropin greater than 10IU/L can determine pregnancy, with the prolongation of pregnancy HCG will gradually increase. The HCG can reach about 400 IU/L in about 30 days of pregnancy, and the HCG can double every other day in the early stages of pregnancy, and the HCG can reach 5000 IU/L in 40 days of pregnancy. It is best to go to the hospital regularly to have a blood test for HCG, and according to the value of human chorionic gonadotropin, we can determine whether the fetal development is normal. If the HCG value is low in the early stages of pregnancy, miscarriage or ectopic pregnancy can be considered, further ultrasound examination can be done, ectopic pregnancy requires timely surgery, if it is an aura of miscarriage, progesterone should be used in time to preserve the fetus, bed rest is needed in the early stages of pregnancy, and reasonable supplementation of folic acid is recommended to prevent fetal malformation.
