Hello Josediccus! I understand that building hemoglobin is not cheap. I had to deal with this some time in 2022 and I would like to recommend 2 vegetables to add to your diet, I believe it won't be expensive, though you can confirm.
Try to add Spinach and beetroot, especially spinach, it really helped me boost my hemoglobin and for the beetroot, I some times add to my meal or blend it with watermelon, cucumber, and carrots, it really helps.
You will be fine, take care.
