What is the progesterone level at four weeks of pregnancy?

Pregnancy, also known as gestation, typically features progesterone levels ranging from 19.4 nmol/L to 95.4 nmol/L at four weeks of gestation. However, specific values may vary among individuals. The details are as follows:

Progesterone is a natural hormone secreted by the female ovary's corpus luteum. It stimulates endometrial development and creates favorable conditions for embryo implantation, making it an essential hormone during pregnancy. The normal range of progesterone at four weeks of gestation is 19.4–95.4 nmol/L. Insufficient progesterone may lead to poor early embryonic development and should be supplemented promptly. Failure to supplement progesterone in time could result in embryonic developmental arrest and subsequent miscarriage. Pregnant women can take medications such as progesterone capsules or dydrogesterone tablets under a doctor’s guidance to increase their progesterone levels. Due to individual differences, progesterone levels vary among pregnant women and should generally be evaluated in conjunction with the individual's hCG levels.

Pregnant women should ensure adequate rest, avoid staying up late, and maintain a proper balance between work and relaxation. Dietary habits also require attention; consumption of raw, cold, spicy, or irritating foods is not recommended. Instead, the diet should primarily consist of light, easily digestible foods.
