Should I be worried?

Whenever I get my period, it seems to flow a little unusual me. They pad barely has much on it but when I go to wipe it seem like it a mess down there. I don't usually wear tampons but when I do it get it all. When I think it's done, there's still spotting afterwards for another day or two. I never had heavy periods mostly light or medium flows. This seems to be going on for a while and since I'm still getting my period I don't worry too much but I'm trying to understand if my body is trying to tell me something and I'm not listening. Please help!!!
