to test or not to test, that is the question ..

so I have a very irregular cycle & I am 33 days late as of right now , I was supposed to start a period on the 14th . every time I miss a our a couple periods I test, get negative & then I get my period within those next 3 days . I've been moody & tired , anywaysss wanting to eat , nose is stuffy & I have been nauseous every here & there . should I test? or wait if I get more symptoms ?
