Hb 9.3 and ferritin 18.7

Hi, just got my blood test results back and my results are as above. I have horrible exercise intolerance and was feeling constantly dizzy while working out. I was also continuously craving clay. I have brain fog and I am unable to sleep, wake up once asleep and unable to concentrate. I constantly feel hot.

I have started oral iron supplements but should I also consider IV iron supplements?
