Why not ask your Dr?: Presumably, you may be iron deficient. Your physician probably has a plan to re-check your blood count and iron levels at some time in the future. Please get clarification from your physician.

Ask your: doctor. Prenatal vitamins can be taken for long time and is beneficial especially if you are trying to concieve or pregnant
