Hi,
I was diagnosed with this when I hit puberty and started getting my period (which apparently is not super uncommon). I tested "normal" again after 2/3 years and again was diagnosed in pregnancy. I hear its not super uncommon then either, epsecially if you have HG, since the baby takes EVERYTHING from you
I was put on iron again after delivery of my DD. I took it for about 3 months, and finally couldnt take the side effects from the iron anymore. I have not be retested since, but I also take a prenatal with iron (food based), which is MUCH easier on my tummy.
Ive never been overly worried about this. Amenia does make you very tired. Not pregnant, I try to make sure I eat iron rich foods (IE: brocilli, dark green veggies, some red meat, etc).
Good luck
Robin
