Had another blood test yesterday and after only taking less than half the dose they wanted me to my vitamin D has risen from 18 to 32 so I am pleased about that. My ferritin was 8.1 when they tested me 6 weeks ago and since then I have had a heavy period lasting 4 weeks. I have been taking an over the counter iron supplement (only 14mg) and yesterday it had risen to 9.8. I asked the receptionist about my hemoglobin and she said it was 24, I assume she read the results for my mean corpuscular hemoglobin instead of just hemoglobin. I phoned back to check as 24 would be very low for hemoglobin and it is 102, so on the a little on the low side. But my worry now is that the doctor has asked to see me but her next appointment isn't for 2 weeks. So I now have 2 weeks to think all sorts of things.
