Hopefully you feel better soon! Have they done any bloodwork to see where you are at? It takes awhile for your body to use the newly replenished iron stores and see an increase in your hemoglobin levels. I had an iron infusion, 1 month later my hemoglobin had increased, 2 months later it had increased once again. Unfortunately, in my case, at the 3 month mark hemoglobin started to decrease again and I’m slated for another infusion.
