The value of HCG in the early stages of pregnancy can correspond to the number of weeks of pregnancy, but it cannot correspond in the middle stages. The HCG value in the body is about 5-50 IU/L in 2-7 days of pregnancy, about 50-500 IU/L in 1-2 weeks, and about 500-10000 IU/L in 3-4 weeks, which is normal as long as it is within this range. The HCG value in the body is 1000-50,000 IU/L in the 4-5 weeks of pregnancy and 10,000-100,000 IU/L in the 5-6 weeks of pregnancy, and normally the HCG value in the body will reach the peak in the 10 weeks of pregnancy, and after the 10 weeks the HCG value will decrease slowly. It is recommended to go to the hospital regularly for examination.
