TMI PICS BELOW 50 days late and spotting! (TMI pics)

Cycle day 84 and 50 days late. Yesterday I thought I was starting my period Because I went to the bathroom and there was a little blood. Which is normal for when my period comes only over the course of a few hours it normally gets heavy. It's been that way since my periods first started. But here it is still very light. It hasn't filled up a tampon at all and normally I have to use super ones because my flow is so heavy. Could I have ovulated really really late? Could this be implantation bleeding? Also, I woke up feeling funny today. Like I'm getting a cold or something. Should I test again or wait
