Phases of bad luck happen, do you mean you have bad luck since week 1 or for 1 week? This can make a big difference to the severity of it.
Everyone has patches of bad luck, most are caused by ourselves...nothing supernatural.
Why don't you use your own good luck spell, the one you posted to the site?
If you already have one that you have written, why not use it; spells written by ourselves are far more effective than those given to us by others.
