i also recieved a blood transfusion after my DD2 birth, 2 units due to PPH, i greatfully excepted it as im not sure how i would have coped post birth had i not! i was extremely fatigued. i also continued to see my TCM and have accupunture and herbs for a few weeks post birth in order to increase my blood supply. if i were you then perhaps look into either storing your own blood or seeing a TCM before and after birth
