At 14 weeks pregnant, why is the progesterone still low?

Patient's question:

No

Doctor's answer:

It is recommended to supplement with progesterone. Your progesterone level is too low, and the risk of threatened miscarriage still exists. It is advisable to take it under the guidance of a doctor. Folic acid and calcium supplements should also be taken on schedule, and nutritional intake in diet should be supplemented. By raising your progesterone level yourself, you may not need to take progesterone supplements anymore. Wishing you a healthy pregnancy.
