heh, it bet it's actually normal.. it is releasing all the toxins and that does some stuff when it comes to hormones.. dont worry. your body should just be cleansing itself from the overload of toxins.. atleast you're not a guy.. you could have hair falling out instead.... then again, how should i know what pms is like.. :| .
dont worry. eventually it should be better
i read a post about this earlier. it happens(not sure what happened with increased breast size, but i think it has something to do with the estrogen)
