@Nammu - I also take an iron pill (65 mg) though I take it nightly. It has to be a certain brand though; other brands seem to cause me issues with constipation. This time around the iron pills nudged my iron up a bit. In the past though, I've twice needed to get iron infusions which wasn't much fun. I don't donate blood (even giving vials of blood for medical tests has caused me to faint in the past, I just don't know, the whole thought of it makes me so queasy and light-headed), and my periods are not heavy at all; I'm not a vegetarian. I'm not quite sure why I have iron issues, neither are the doctors. Again, it's idiopathic.
