I Went To The Doctor For What I Believed To

I went to the doctor for what I believed to be ringworm, and was told that I was correct, the ringworm is present only on my arms, chest, lower stomach area, buttocks, and one big ringworm on my right leg. I was prescribed 100mg itraconazole, I was told to take them twice daily until gone, which I have been doing for the last 6 days now, I only notice some getting lighter but not going away, should I be concerned with only two pills left?
