The normal value of HCG in the 5th week of pregnancy is about 1000-50,000mIU/ml. Each person’s body condition is different, so the rate of HCG growth after pregnancy is also different. In the first 8 weeks of pregnancy, the HCG growth rate is relatively fast, which can maintain the normal growth and development of the fetus and avoid various problems such as fetal miscarriage. After the 8th week of pregnancy, the HCG value in the body will gradually decrease and reach a relatively stable state at about 20 weeks of pregnancy, basically at the same level. It should be noted that the HCG value in the body changes a lot in the early stage of pregnancy, so it is necessary to go to the hospital for regular checkups. If the HCG remains the same or grows slowly, it is best to have timely treatment to avoid problems such as fetal abortion or ectopic pregnancy, which can affect women’s health.
