This systematic review of published studies of progesterone or progestogens for treatment of PMS found a small positive effect of oral micronized progesterone over placebo in the 3 trials that studied this.  No published studies of progesterone cream were found.  A statistically, but not clinically, significant improvement was seen with progestogen treatment.
