should I take a test?

so eve says I'm late 25 days.. me and my fiancé aren't using any type of birth control, but my period has never really been normal enough for me to track. should I just keep waiting for it to show our should I take a test and find out? I don't feel pregnant but then again I wouldn't know how that feels so.... I just don't want either of us to get our hopes up just to be disappointed with a negative test idk what to do
