The level of human chorionic gonadotropin in the blood during the 5th week of pregnancy is relatively small, ranging from 1000-50,000 IU/L. As the gestational weeks increase, the level of HCG in the blood gradually increases, reaching a peak around 8-10 weeks of pregnancy, and then gradually decreasing to a certain level that lasts until late pregnancy or even until after delivery. If the level of human chorionic gonadotropin does not increase continuously, a low level of increase can lead to miscarriage or ectopic pregnancy. If the increase exceeds the normal level, you need to be alert to the possibility of gravidity, and you need to monitor the hormone level in the blood after pregnancy to avoid accidents. After pregnancy, you need to pay attention to rest, observe whether there are any abdominal pain, vaginal bleeding and other uncomfortable symptoms, and strengthen the intake of nutrition to avoid affecting the baby’s development.
