In brief: Prostaglandins
Most likely prostaglandins (pg, ) which are derivatives of arachidonic acid.
Pg cause menstrual cramps, and can be associated with nausea, diarrhea, and mild temperature elevations - among other things. Pg rises dramatically before menstruation and peaks during your period. Otc drugs like Ibuprofen block pg; you might find it helps with your nausea.
