After pregnancy, due to the different activity of each patient’s gestational sac, the values of HCG and progesterone vary greatly, and there is no uniform standard. We mainly observe the changes in the values of the two hormones after the patient’s pregnancy to determine whether the embryo is developing normally. After pregnancy, progesterone is more normal if it is greater than 20ng/ml, it is more normal if it reaches between 30-40ng/ml in about 40 days of pregnancy, and it is normal if it is not less than 25ng/ml in the first 90 days of pregnancy. When the value is between 4000-6000miu/ml, it is normal to double once in 3-5 days. As the value of HCG increases, the rate of doubling will slow down, and it will be very good if it can reach 100000miu/ml by about 60 days of pregnancy.
