Clinical data suggests that progesterone <5ng/ml, can be considered abnormal embryonic development or sterilization. However, low progesterone alone does not usually lead to embryonic failure, but is mostly caused by the abnormalities of the embryo itself. Progesterone is an important progesterone that supports pregnancy in women, and low progesterone is often indicative of luteal insufficiency, which may lead to embryonic arrest or miscarriage. Women's progesterone values vary at all times of the pregnancy week, ranging from about 63.4-94.5nmol/l in early pregnancy. The range of progesterone values itself fluctuates greatly after pregnancy, and a low value may indicate delayed embryonic development or even sterilizations, while a low progesterone level without other abnormal symptoms may be considered a healthy embryo. If the value of progesterone is too low in the course of pregnancy, you must not take progesterone drugs without authorization, and you should go to the obstetrics and gynecology department of the hospital as soon as possible, and listen to the doctor's advice to decide whether to preserve the fetus. In addition, in daily life, it is recommended that pregnant women try to eat more foods rich in protein and reduce the intake of stimulating foods.
