I have tear drop shaped cells also. I have low white count, platelets, and hemoglobin. I have high monocytes.?

I have low iron levels too. I have had a history of anemia and low platelets for approximately 10 years. I have had iron infusions in the past. I now have tear drop shaped cells and fatigue and bone pain. The lab report says that the findings are sugetive of inadequate hematopoiesis by bone marrow. Can someone explain what this means please?
