Anemic and so exhausted.

I had my H&H drawn on Tuesday, and it showed I'm anemic. Hemoglobin 11.1 and hematocrit 32.5, which isn't terrible, but still a huge drop from my baseline of 13.3 & 39. I have been soooo exhausted lately. Absolutely no energy. I see my doctor on Tuesday. Who else out there has anemia? Were you put on any supplements?
