Mid-cycle or Implantation bleeding?

Hi everyone! I'm new to this group but not new to PCOS. I'm trying not to get too worked up about this so I was hoping to talk to. I can't lie, I have no idea what cycle day I'm on because one we passed 4 weeks late for my period I stopped tracking, it was just too frustrating with every negative test. I believe I'm now I the 8th week of this cycle. I started spotting 3 days ago, it's been coming and going but hasn't really been any heavier. It's mostly been kind of watery and has gone from being light brown to light pink back to light brown. This is nothing like any period I've had before. I don't usually get mid-cycle bleeding and to me it seems a little late for it (though it also is late for everything). Only mild discomfort on my right side and it's not constant. So for those of you who have experienced this, does this sound more like mid-cycle or Implantation bleeding? And how long would you suggest I wait to take another test?
