Does it take to become anemic again? I went to the dr a few weeks ago and they said that my iron was fine. But recently I have been bruising a lot more and have noticed that I feel tired and am pale. I don't have my period right now, or else I would assume that was what was causing it. I was just wondering if anyone knew how long it took for iron levels to drop again. When I first got diagnosed a few months ago my ferriten level was 3 and my crit was 32. So I don't know if that makes me more predisposed to my iron dropping or what.
