Could this be anemia?

Of course I will go to a doctor, Im just wondering if what Im feeling could be anemia. I feel totally exhausted, my heart race has increased even at rest, I get out of breath very easily. I also feel my muscles tired/weak more easily, the kinda feel you get when tired at the gym. My head has been hurting almost every single day and my eyes looks very pale. Sometimes I feel like Im going to pass out, like what you feel when you are having hypoglycemia. My last blood test is from september, everything was ok except that my hemoglobin (12,6 g/dl) and ferritin (13,7 ng/ml) were borderline from being low and vitamin c and d were also low (I went to the doctor then and Im taking vitamin d and c tablets). Iron levels were normal (135 mcg/dl).

UPDATE: Thank you so much for the replies! I went to doctor again and got retested, my ferritin in fact did get lower, it was 12. I got prescribed B12 shots and iron infusions first, then oral supplements afterwards. Hope it will get better soon 🤞
