I have very small whiteheads with only 3 days left on Isotretinoin? Should I not be complely free at this stage?

My response to this medication has been fantastic so far, in fact after the 2/3 week I was COMPLETELY CLEAR. I took x2 Months@20mg/d then, x2 Months@40mg/d, then a 43 day gap of NO TREATMENT. then x1 Month@20mg/d and now just finishing x1 Month@40mg/d. Please note: The dermatologist told me 4 months might clear my skin, and it certainly did, but my back and chest was the reason for further 2 months treatment. WAS THERE TOO LONG OF A GAP (43 days)? (waiting list in the dermatology center)
