Answer

It is more common to say "ruining your pans" or "spoiling your plans". "upset" is not the best choice here, since it normally refers to disrupting something that is happening. A plan refers to something not happening at the moment.

Answer

Yes, this sounds fine to me.  I think it would be more common to say "upsetting your plans", but your statement is perfectly grammatical and understandable.
