This is Dr. David
I am sorry you have not been feeling well.
where you put on iron supplements?
where you anemic? (low red blood cell count?)
you need to have your stools tested for blood. you could be loosing blood through your stool.
if your iron level is low, you need to go on supplemental iron and have your stools tested for blood since the bowels are the most common place to loose blood slowly.
you need also to have your folate levels checked as well.
low folates can also cause anemia or low red blood cell counts.
let me know if you have questions.
