What are symptoms of Iron deficiency and B-12 ? - iron deficiency symptoms more condition_treatment

I had a blood test 4 months ago and the doctor told me I had an iron deficiency or vitamin B12, I stopped taking supplements is not because I want to take, too.
Ive had many different symptoms, I am not sure whether they are due to a shortage.
So I started again for additions atleast five days and I feel better, but how long until I complete results?
