Iron deficiency vs. Iron deficiency anemia- what is going on with me???

Hi everyone, this is my first time posting. I've tried to do some research on my own, but I am at a loss. I will start out by saying that I had a baby back in April 2014 at which time my other labs were within normal limits except for my Hgb and Hct (7 and 24 I believe). I recently followed up with my primary care doctor for symptoms of chest pain, shortness of breath (especially with exertion), and the biggest symptom- extreme fatigue. When I get up in the morning I feel like I've never slept, and by the afternoon I feel like I need to go back to bed for the rest of the day. I realize I have a 3, almost 4 month old baby, but she sleeps through the night for the most part, so it's not like I'm not sleeping at all through the night. I had labs drawn last week and the main results were as follows:

Ferritin, Serum- 7 (15-150)
TIBC- 415 (250-450)
UIBC- 368 (150-375)
iron saturation- 11 (15-55 %)
iron, serum- 47 (35-155)
rbc- 4.93 (3.77-5.28)
hemoglobin- 11.5 (11.1-15.9)
hematocrit- 37.5 (34.0-46.6)
mcv- 76 (79-97)
mch- 23.3 (26.6-33.0)
mchc- 30.7 (31.5-35.7)
rdw- 17.1 (12.3-15.4)
platelets- 317

WBCs, Thyroid, B12, and HgA1C all looked good. From what I've read, it seems that I may have iron deficiency, but because the hemoglobin and hematocrit are within normal limits it is not classified as anemia. What I don't understand is I just spoke with my Dr. office, and the nurse said the doctor checked off my lab results and didn't put a note in that she needed to see me for a follow-up. The nurse asked me if I had any concerns about my lab results. I guess I'm just not sure if my lab results are "off" enough to be causing my symptoms, or if something else is going on. Should I be started on iron supplements? I'm just not sure where to go from here. Any help would be appreciated. Thanks!!
