In brief: Prostaglandin

Most likely the cold is from a release of prostaglandin from your menstrual lining.
If you are not allergic to Naproxen (aleve), try blocking it with aleve, (naproxen) one pill in the am and pm starting a couple of days before your menses starts, continuing though the menses. If the chill is accompanied with shakes and a fever, see your doctor and stop using tampons for menses until you are examined.
