Implant bleeding or af coming?

My usual cycle is 30days, Lmp- 7/21 making today CD 34.. danced a few times during O week, currently 4 days late had 2 days of this and nothing more.. CM is white creamy and no more or less than usual.. Minimal sore nips, a few random tiny cramps that go away.. Tested BFN cd32.... Do you guys think AF is coming? Or does this seem like implant bleed?
