Progestin is too low, not recommended to protect the fetus

Low progesterone levels during pregnancy indicate that ovarian luteal function is insufficient, and abortion and threatened abortion are prone to occur. Secondly, low progesterone will also reduce the quality of the embryo, even if forced abortion may still cause fetal growth and development defects. If the embryo development is poor, it is not recommended to inject progesterone to protect the fetus.
