Anyone else anemic?

Mariah

I had my glucose test yesterday and I passed that but then I get told I'm anemic and I'm going to have to have an IV iron infusion. Has anyone else had one? What's it like? My first pregnancy at 18 I had to take Iron pills but my Dr said it's bad enough I need the IV to keep me from having a blood transfusion at birth with me having a c-section.
