HCG is usually more normal between 20 and 50 IU/L at two weeks of pregnancy. HCG refers to human chorionic gonadotropin, which is important for diagnosing early pregnancy. At two weeks of pregnancy, the value of HCG may range from 20 to 50 IU/L. The value of HCG varies from woman to woman after she is pregnant and this value fluctuates in a wide range after pregnancy. Usually an HCG value greater than 25 IU/L is highly suspicious of a pregnancy. If the HCG value suddenly decreases, there is a possibility of miscarriage; if there is an increase in HCG, it may indicate that there is a possibility of hyperemesis gravidarum, teratoma, ectopic HCG-secreting tumors and so on. It is recommended to go to the hospital for examination in time and clarify the cause with the help of the doctor. Women who are two weeks pregnant should pay attention to keep their mood happy, avoid lifting heavy objects, eat more high-protein, vitamin-rich foods, and consult a doctor promptly if they feel unwell.
