Answer 2

The past perfect continuous tense of this given sentence will be –

My doctor had been advising me.

The past perfect continuous of a verb can be written only by the addition of had been, where ‘had’ denotes the past perfect tense and ‘been’ is exhibiting the continuous tense of this changed sentence structure.

So, together these words accomplish the past perfect continuous tense of the given verb.
