What are the reference values for hCG and progesterone at 31 days of pregnancy?

At 31 days of pregnancy, the reference value for hCG is generally 100–5000 mIU/mL, and the progesterone reference range is typically 15–40 ng/mL. Both hormones should rise in coordination to support embryonic development. If hormone levels significantly deviate from the normal range or show abnormal growth patterns, prompt medical evaluation is recommended.

hCG is a key indicator for early pregnancy assessment. At 31 days gestation, which is shortly after embryo implantation, hCG levels rise rapidly, typically doubling every 48–72 hours. An hCG level between 100 and 5000 mIU/mL often indicates normal initial embryonic development.

Progesterone helps maintain a stable endometrium and supports embryo implantation. At 31 days of pregnancy, progesterone levels should be at least 15 ng/mL, with an ideal range of 25–40 ng/mL. Levels that are too low may increase the risk of threatened miscarriage, while excessively high levels warrant evaluation for possible abnormal pregnancies.

During pregnancy, it is important to maintain regular sleep patterns and avoid staying up late, eat a balanced diet rich in folic acid and protein, avoid strenuous exercise and emotional fluctuations, follow medical advice for regular hormone monitoring, and refrain from self-comparing test results or excessive anxiety.
