but you shouldnt be a dumbass, if your chick is having health problems, dont put it off. yes, i think the vacc can effect people's moods, if it screws with fertility, then presumably it could be fucking with people's hormones too, and if her diet and moods are fucked up concurrently, it might be something worse. dont wait to find out. ask her about if her cycles and food desires have been any different, and report back, plz.
