"I take 54mg of elemental iron a day,"

Too much iron is not good. Aside from toxicity of excess iron, iron can boost the growth of bacteria and other pathogens.

"I often have anemic really cold day or 2 out the week, every week!
for 1-2days out the week i will wake up very cold and body temp can be 94-95 but usually its 98ish so does flucuate abit."

One of the causes of low body temperature is copper deficiency.
Iron deficiency anemia might not be due to too little iron, but to a copper deficiency. Copper is necessary to properly metabolize iron.
