What is the reason for the progesterone level being lower than the previous check?

Patient's question:

No

Doctor's answer:

According to the situation you described, if you are not pregnant, it is mostly due to endocrine disorders; if you are pregnant and have low progesterone, it is more likely caused by luteal function decline. It is recommended to supplement progesterone in a timely manner. You can take or inject progesterone to prevent miscarriage and get more bed rest.
