I wish we weren't doing... & I wish we wouldn't be doing...

[IXIA]

In my grammar book it's written that "wish" can express "regret that something is not the case" and also "unlikely or hypothetical situations".

The example in the book is:

"I wish we weren't doing the exam tomorrow!" expressing regret about the future.

I want to know if it's correct to say:

"I wish we wouldn't be doing the exam tomorrow" expressing a wish instead of a regret. I'm considering this possibility because I know that it's said "I wish he would do the shopping" and I don't know why it can't be the same with the other example...

I hope I've explained properly my question :S

Thank you!!!

Ojalá no hicieramos el examen mañana: I wish we weren't doing the exam tomorrow. [regret]
Ojalá hiciera la compra: I wish he would do the shopping. [wish]

In answer to your question, the "I wish + would" construction is allowed with one but not the other because one is a wish ("would" allowed) but the other is a regret ("would" not allowed).

I think that my problem was that I was considering "regret" as something that I have done but now I realize that I shouldn't have done it, instead of something that I have to do and I don't want to.

Thank you for your help and for your quick answer!
