Iron deficiency when will I feel better?

It's a struggle to even think about doing anything. I have low ferritn low iron saturation, low vit D, low calcium, and low B12 - doctor thinks it's from a vegan diet. My doctor didn't say how much to take, just said "get supplements" so I've been taking one of each a day and the iron every other day to make sure I don't have side effects but I still feel bad. It's only been two weeks though. How long does it take?

how are you feeling ? how low is your iron

I have the same question. My ferritin level was 8 when I started on iron supplements about two weeks ago. Some slight improvement, maybe, but overall I still feel pretty bad. Would love to know how long it’s supposed to take.
