Implantation (TMI)??

Ch

5 days ago I experienced what I thought what implantation bleeding after peeing. Saw a bright red in the toilet, wiped and saw it on tissue. Nothing after for days. Until today which is CD 28 I saw a more mucus like discharge after peeing with a brown tinge. Could this have been part of implantation too? Or is AF coming? I’ve never seen this before.
