Dr. Fredholm might want to contact Dr. Hale. I know that he and Dr. Hartmann just concluded some research into the use of metaformin (milk samples, etc) and though the work isn't published yet, Dr. Hale may be able to reassure you about that drug. I don't know much about the specific dosages of progesterone for tx in PCOS, but with a 14 mo. old the dose may not be terribly significant this far from partuition. Progesterone at this point may not have much affect on lactation if it mimics (as I would assume) the normal values required to initiate menses. Many women menstruate and lactate simultaneously.
