21w, fatigue and low (ish) ferritin

As per title I’m 21 weeks and since recently started feeling dizzy and tired, like 1st trimester tired but a slightly different flavor. The iron deficiency test showed that my ferritin went from 60 in February to 26 now. It’s still within norm according to the lab although multiple sources cite <30 as iron deficiency.

The trick to all that is that I have mild hemochromatosis and as of now not taking any iron supplements at all. Not even as part of prenatals. My hemoglobin is 11.8 so on the lower side but still above 11.1 threshold. I feel like even though it’s still norm it’s clearly going down and I might want to start with supplements without waiting for it to become really problematic. My doctor is adamant that my symptoms have nothing to do with low iron because everything ‘normal’ and is lecturing me on blood sugar and carbs consumption. I feel gaslit and the one taking crazy pills…. Or am I overly dramatic? Any personal experience or advice would be appreciated!
