When speaking with the past perfect tense, we often contract the subject and auxiliary verb:

I had
I'd
you had
you'd
he had
she had
it had
he'd
she'd
it'd
we had
we'd
they had
they'd


The 'd contraction is also used for the auxiliary verb would. For example, we'd can mean:
  • We had
    or
  • We would
But usually the main verb is in a different form, for example:
  • We had arrived (past participle)
  • We would arrive (base)
It is always clear from the context.
