Should I or shouldn't I?

So the past few months my period has been a bit of a mess. Started out normal then about 4 days or more after ending I'd experience very light bleeding here and there. This past one however has me wondering..... it lasted a full week and the WHOLE time it was nothing but super light. Like to where I'd almost never find any on the pad just when I would wipe. My breasts have also stayed sore even since it finished.... I don't want to jump to the conclusion and get a test just yet because I'm tired of seeing that negative test result again and again.... but what do y'all think.... is it possible or.... is this normal being I'm going on 30?
