Has anyone used otc progesterone cream? Which one is the best and what side effects (if any) did you have? I have a progesterone deficiency and am looking into the creams, however, it scares me a little bit. The warning on the side said "known to the state of California to cause cancer". I mean...thats a little stupid right? JUST California recognizes that?? And I thought progesterone is natural...did it just mean if it is overused?
