I'm already on Prozac for something else; it doesn't seem to touch whatever happens to me around the time of my period. I once went on birth control meds for a month to see if that would help, and wound up crying uncontrollably literally all the time instead of for only 2 weeks out of the month; for the 2 weeks I do have my period it basically feels like I'm on those birth control meds again. I don't know what my options are, and since all my tests (thyroid, hormones) come back within normal ranges there is little my doctor can do.
