After ovulation and corpus luteum formation, this increases to 20 to 30 mg/day. Normal levels of progesterone during pregnancy are as follows: In early pregnancy normal levels of progesterone are: 1 – 28 ng/ml (3.18 – 89 nmol/L) During the first trimester normal progesterone levels are: 9 – 47 ng/ml (28.5 – 149 nmol/L)
