Im on day 5 today, having little to no sides, I get minor shakes, but nothing major.

Shouldnt my temp be going up? Ive been checking it a few times a day and its not even 98.6, more like 97 or so. When i work out i sweat like a mofo but my temp doesnt seem to be going up at all. My question is, is clen doing anything for me if my temp doesnt go up?
