Girls, could you please tell me how to proceed? At the beginning of pregnancy, there was low iron levels, the doctor said that in the third trimester she would prescribe drugs, but I changed doctors and the new doctor is silent. She said my hemoglobin is normal and doesn't need anything to be taken. Has anyone encountered this? After all, iron is an important element for pregnant women.
