OB or IB that's the question!

So at around 5 or 6dpo I have been experiencing light pinkish/brownish spotting mixed with my cm. It lasted 3 days....

I'm not sure if it's Ovulation bleeding or implantation bleeding (maybe none of the above). My period can be irregular at times hense I don't know. Maybe I ovulated later then I thought.

If this sounds familiar to anyone I would appreciate any advice/comments.
