Large chunks/clots of blood during period?

For the past few months during my period I’ve been passing large chunks/clot looking things. I don’t bleed heavy, but when I pass these chunks/clots I can fill a pad with blood in no time at all. I do pass a chunk or so every hour for only ONE day and then i’ll have very little to no more period following. What could it be?
