How many days after pregnancy does the placenta secrete progesterone?

Patient's question:

No

Doctor's answer:

Hello, even in a non-pregnant state, there is progesterone in the body. Generally, the progesterone level is relatively low before ovulation, which is during the follicular phase. After ovulation, progesterone increases. During pregnancy, the progesterone level typically ranges between 63.6-95.4, and it generally gradually increases as the pregnancy progresses.
