The normal range of progesterone value at 8 weeks pregnant is 20.7-36.5ng/mL. Progesterone value is an important indicator of the physical condition of a pregnant woman during pregnancy. Generally speaking, a progesterone value greater than 20ng/mL in early pregnancy can maintain a normal pregnancy, promote the growth and development of the fetus, and avoid miscarriage and other conditions. Each woman’s health condition is different, the value of progesterone will also be different, some women’s progesterone value can be up to 40ng/mL. However, it is not the case that the higher the progesterone, the better the embryo. If the level is low, whether to supplement progesterone needs to be decided by the doctor in conjunction with the progesterone level and other factors. If the progesterone level is too low, if not handled in time may lead to fetal growth and development stagnation, clinically can follow the doctor’s instructions through the oral progesterone drugs to improve the progesterone value.
