This isn't a period so what is it.

Earlier this month I had a 4 day light period that I only needed a panty liner for. I never even soaked the panty liner. Here I am again a week later doing the same thing. This is day 2 of it but the blood isn't even coming out of me and onto the panty liner. If I stick toilet paper up there and wipe there's blood but not a lot and I'll cramp out of nowhere but it just doesn't feel like a period? It feels different like something is wrong with me. Any idea of what it could be?:/
