I don't know if I should test

So my period has been really light. I know my periods are light, but right now it's just spotting. I normally have dark blood that is full of clots (sorry tmi) but it's pink and it's only when I wipe. I thought I was starting my period so I put my cup in over night and I thought it would have been full. But there was hardly anything in there. It's now the second day of this and I need all of your advice?
