Got border line iron level in second opinion

Hi Mommies I’m 32+4 weeks pregnant and experiencing lot of fatigue and severe frequent headaches My current OG said it’s normal and asked to take Panadol Also he said I’m not anaemic (iron level is fine ) It didn’t help much hence I went to other OG for second opinion n turns out my iron level (ferritin =29) n Vit B12 =157 is in border line New OG asking me to take supplements through IV but I’m scared if I should ask my old OG about the same and show him report of iron deficiency Is it ok to share this with old gynae or will it cause issue since he will be the one doing my delivery so would it offend him 😞?
