The possibility of pregnancy needs to be considered when human chorionic gonadotropin is higher than the upper limit of normal, about 10 mIU/mL, and the value of human chorionic gonadotropin in the blood varies depending on the time of the pregnancy. The hormone can be detected in the blood around the first week of pregnancy, and as the weeks of pregnancy lengthen, the value of human chorionic gonadotropin in the blood gradually increases, reaching a peak at 8-10 weeks of pregnancy. Abnormalities in human chorionic gonadotropin, especially low levels of the hormone, can lead to miscarriage, and if the hormone is too high, trophoblastic diseases need to be considered. Early pregnancy requires regular monitoring of hormone levels in the blood, which can effectively determine whether the pregnancy is normal, pay attention to rest and avoid excessive exertion.
