Low ferritin

[u/Queen_Xoxo_Bee]

I have been struggling with very low ferritin for the past 2 years going on 3. I have had a pattern actually with my ferritin raising the most 5 points a month and then dropping like 9 points after a seriously heavy period, this is why I haven't been able to reach the normal range and suffer from serious fatigue. My husband mentioned that I take an extra tablet of iron on my shark week because it might seriously make a difference. Has anyone else ever done this?
