Why do I keep getting a fever with my period?

I know that some women do get fevers as a part of their period, but is it normal to get high fevers? I have never had a problem with my period before, but the last two periods have had me chilled, feverish, and with a temperature of up to 102 degrees Fahrenheit, I couldn't even go to work or anything for like a week. I don't use tampons, and I'm not sexually active. I am in pretty good shape. Please tell me I won't have to take a week off of my life every month from now on because of these awful fevers. Is there anything I can do?


Is menstrual synchrony fact or fiction?

Okay, so my mother does not believe, as I do, that when a group of women live closely together (i.e., in a dorm setting) that their menstrual cycles become roughly similar, due to the release of pheromones. I'm pretty sure that I heard this somewhere, but I can't find anything to back it up. I swear I'm not making it up, but my mom doesn't believe me.

Thanks for your help.
