It could be the flaxseed or cocoa butter. It seems like you already have too much estrogen, and your body is sensitive to it. You might want to test fenugreek because it is both estrogenic and the opposite which is progestogenic (don't know which of its effects is stronger). Test if asparagus, milk thistle, or hops lowers your menstruation (and estrogen) problems. I wouldn't take the above advice that mentioned menopause, I don't know how serious that is.
