It increases thereafter from gestation weeks 7–9 (mean serum progesterone in week 7 = 63.4 nmol/L, compared to 67.7 nmol/L in week 8 (p = 0.374) and 78.9 nmol/L in week 9 (p < 0.001).

When does progesterone plateau in pregnancy?

Similar to estrogen, your progesterone levels will peak around 32 weeks. This may cause some women to experience acid reflux or heartburn.

What is considered low progesterone at 7 weeks?

Between the sixth and eighth weeks of pregnancy, doctors consider low progesterone levels to be less than 10 ng/ml, which is a sign of an abnormal or ectopic pregnancy. In the remaining trimesters of pregnancy, progesterone levels continue to increase to 150 ng/ml.

What is the range of progesterone in early early pregnancy?

Pregnancy 1st trimester: 11.2 to 90.0 ng/mL or 35.62 to 286.20 nmol/L. Pregnancy 2nd trimester: 25.6 to 89.4 ng/mL or 81.41 to 284.29 nmol/L. Pregnancy 3rd trimester: 48 to 150 to 300 or more ng/mL or 152.64 to 477 to 954 or more nmol/L.

What should progesterone be at 8 weeks?

Maternal serum progesterone levels rise slowly to 40 ng/mL near the end of the first trimester and then increase progressively to reach 150 ng/mL, at term. Low levels of progesterone (less than 10 ng/mL) at 6 to 8 weeks signify an abnormal intrauterine pregnancy or an ectopic pregnancy.

What level of progesterone causes miscarriage?
