What should I do? 14 DPO

So yesterday when I wiped I had very very light pink on the tissue. My period is supposed to be today so usually when I see the pink my period is about to come so yesterday I went ahead and put a tampon in. There was barely any blood. It was kind of red with brown and discharge. Then this morning same thing there was little spot and then this afternoon I changed and still no full on period. This never happens usually when I get a tiny bit of something my period comes on full blown the next day. What do you guys think? Should I wait another day and see what happens or test in the morning? 12 DPO was Sunday.
