I have come across the sentence below and I am confused is "she would had"  or "she had had"? Complete sentence is below:

She’d had this problem, local anaesthetic resistance.

Answer

It is short for 'she had had this problem'- which is the pluperfect tense.

When you look at contractions look at the last letter: 'd means short for 'had', and 've means short for 'have'.

(She would had does not make sense)

Answer

It's a contraction for "she had had".
