After pregnancy, the level of Hcg in a woman’s body is constantly changing, and the serum HCG value varies greatly from week to week and from one pregnant woman to another. It is normal for a pregnant woman to have an HCG value of between 15,000-20,000 IU/L at seven weeks of pregnancy. HCG is the value of human chorionic gonadotropin, which is measured in a woman’s blood through a blood test to determine whether she is pregnant. There is no standardized HCG value after pregnancy, and it will change gradually with the woman’s pregnancy weeks. It is normal for the HCG value of a pregnant woman to be between 15,000-200,000 IU/L at the seventh week of pregnancy. If the HCG value of a pregnant woman is too high or too low, further examination is needed to determine whether it is normal or not in conjunction with the results of the ultrasound examination. If the HCG value of the pregnant woman is much higher than 200000IU/L, ultrasound or color ultrasound is needed to rule out the possibility that the fetus is suffering from hyperemesis gravidarum. If the HCG value of the pregnant woman is far below 15000IU/L, it may be related to the actual gestational week is small, the quality of the embryo is not good, or the development has stopped, etc., and it is necessary to consult a doctor in time for targeted treatment.
