Progesterone Support in PregnancyAt 26 weeks of pregnancy (in the second trimester), normal serum progesterone levels typically fall within the range of 19.5 to 82.5 ng/mL or 62 to 262 nmol/L. These levels will continue to rise and will be maintained to support the baby's growth, prepare the breasts for milk production, and prevent premature contractions.
