late then spotting then weird period😕

  So my period was 8 days late. Then Wednesday I began to spot for 3 days. The night of the 3rd day my period came.but it was still light. Usually 3 days in it gets heavier. It hasn't. Now it's like bright right still some clots but normally by the fourth day it starts to lighten up. I'm still having cramps which I normally don't get. Idk what's going on with me! What do you guys think ?
