36To evaluate whether daily oral micronized progesterone is effective in preventing recurrent spontaneous preterm birth (RSPB) and whether micronized progesterone use increases maternal serum progesterone levels.
To evaluate whether 400 mg daily oral micronized progesterone from 16 to 34 weeks' is effective in preventing recurrent spontaneous preterm birth (RSPB) and whether micronized progesterone use increases maternal serum progesterone levels.
oral micronized progesterone = 400 mg oral micronized progesterone nightly from 16 to 34 weeks
Identical Placebo tablet = placebo taking nightly from 16 to 34 weeks
