Thanks. I get a feeling that it's going to remain a mystery!! They won't give me iron if I do get anemic as the blood thing they think I have affects the size of my red blood cells. Physically I can't process any more iron because my blood can't take anymore on. My mum was given blood transfusions when she was pregnant w/ me. If I don't have that then the other theory is that I am B12 deficient which again means extra iron is useless as my body can't process the iron. I'll need to have some B12 shots. My mum was diagonosed with this in her last pregnancy. When I got my booking bloods back she said it made her experiences make a lot more sense! All of us sisters have been borderline anemic or anemic at some point, so it would be great if we knew why, but apparently the tests are expensive, and I guess not necessary unless you're dangerously ill.
Your levels sound very low Hun, so no wonder they want you to keep going with the iron. Do you feel any better now?
