Iron at 33 weeks•

At 29 weeks I got informed that my iron was very low, at an 8.8. Of course they automatically put me on iron pills taking them twice daily. I went to L&D two nights ago, seeing as my doctor told me I had to go immediately, (over the phone). She ran a full iron panel, my hemoglobin was at 8, doctor said the very minimum should be a 37. My hemocrat is at a 4.7% & the lowest is supposed to be 20%. Can someone inform me as to why I'm not seeing high risk? It is steadily dropping. And nothing is helping!
