Talk to Gynecologist on CBC Report In Pregnancy

Its my first pregnancy.I am currently 34 weeks + pregnant .At 32 weeks my hb was 11.1g/dl and ferritin was 10.74ng/ml.I am on 100mg elemental iron daily along with follic acid and good diet.. At this hb and ferritin there is indication of I/V iron? Should I repeat my hb again at 36 weeks or should repeat early? Thanks
