Answer 2

Answer:

I had finished my work and I went to bed.

When you've placed the Past present tense (finish+ed) the word had is placed and _if you use having_ it is not the correct word in any sentences to use.

you typed (my work I went to bed) this on in indirect form. So you should have the Accent of English.
