Implantation bleeding?

So I ended up ovulating late, like cd 23 and now I’m cd 30 which I should be due for my period any day, sometimes it’s really late. But I’ve NEVER spotted like this before a period or with any other pregnancy so I don’t know what to make of it. Super late last night I noticed some brownish color when I wiped, then today on and off bright pink/red but still very light. Now it’s early the next day it’s turning back to brown and stopping completely? I think I’m still too early to test at 7dpo
