Iron tablet & body temperature

Since I don't eat vegetables properly, my doctor suggested me to take iron & calcium tablets during early pregnancy. After taking it for past two days, my body is so hot at night, I could feel my bed burning coz of my body temperature. I haven't checked temp in thermometer as it's not working. Is there any connection between consuming iron tablet & increase in body temperature?#1stimemom #firstbaby #advicepls
