Possible iron deficiency

C

Got bloodwork back from my glucose test and my doctor noted that my hemoglobin was 12.5. She said that was a little low but that she’d recheck it at 36 weeks. I’ll be 26 weeks tomorrow. That seems too far away to check it again? Should I just start taking iron supplements now? I’m on a prenatal with iron but I’m thinking that’s not enough now. She said normal hemoglobin range is 12-16.
