Is a progesterone level of 11.89 during the first month of pregnancy serious?

Patient's question:

No

Doctor's answer:

Low progesterone levels indicate insufficient corpus luteum function in ovary pregnancy. It can be supplemented through intramuscular injection of progesterone or oral administration of natural progesterone to prevent miscarriage caused by corpus luteum insufficiency in pregnancy. After the third month of pregnancy, when the placenta is formed, its function will fully replace the corpus luteum function of ovary pregnancy. The placenta synthesizes and secretes progesterone to maintain pregnancy.
