Is the supplements working?

Sep 2024 doctor said iron was severely low , she prescribed me ferrous sulfate 325 (65 Fe) MG tablet to take 3times a day. “Missed” (about 2 weeks in a 3 months span) … the pics are from Sep 2024 to now Jan 2025. Doctor said it’s improving so take 1-2 a day now… but I don’t think so
