Anemia Problems and Iron Pills

Patient: I haven’t been to the doctor in 4 years that was my last check-up. So when I went four years ago they told me I had a little a bit of anemia, and reccommended me to take iron pills. I took them for at least 3 months after my check-up. And I completely forgot after that. Now it’s been 3 years without taking the pills. What are the possibilities my anemia has increased?
