What is the normal progesterone level during the first month of pregnancy?

In daily life, many individuals experiencing their first pregnancy are unfamiliar with fundamental reproductive health knowledge. To better assess maternal and fetal well-being, it is essential to confirm that certain biomarker values fall within normal ranges. So, what is the normal progesterone level during the first month of pregnancy?

What is the normal progesterone level during the first month of pregnancy?

During the first month of pregnancy, the average normal progesterone level is approximately 25 ng/mL, with a lower limit of normal at 20 ng/mL—levels at or above this threshold typically do not require progesterone supplementation for pregnancy maintenance. If progesterone falls below 20 ng/mL and symptoms of threatened miscarriage appear—such as light vaginal bleeding and mild lower abdominal discomfort—progesterone support may be indicated. Even in the absence of miscarriage symptoms, progesterone levels below 15 ng/mL warrant progesterone supplementation to support the pregnancy; levels below 6 ng/mL are generally associated with nonviable pregnancy.

In healthy pregnancies, the average progesterone level is typically around 25 ng/mL. Some laboratories report results in nmol/L; in this unit, the normal range is approximately 70–80 nmol/L. 1. Progesterone levels above 25 ng/mL (or >50 nmol/L) are generally considered normal. 2. Levels between 15–25 ng/mL may suggest luteal phase insufficiency, and supplemental progesterone may be appropriate.

During pregnancy, it is advisable to avoid spicy, heavily seasoned, or highly stimulating foods, and instead consume more fresh fruits and vegetables. Maintain regular work and rest schedules, avoid excessive fatigue, prioritize fetal well-being, and attend all scheduled prenatal check-ups. We hope this information is helpful to you!
