I had heavy cramping for two days and tenderness of breasts. I knew I was getting my period. I have had it for two days now along with diarhea. I took my temperature today because I had also been feeling cold or hot (chills or sweats) and tired. My temperature read 97.7 which is low for me. Should I be concerned. I am 38yo f at 118 lbs. No other health problems. Heavy cramping continues with loose stools and heavy clotting. I have no appetite but am still eating and drinking plenty of fluids.
