Do I test again?

Holly

Ok so I'm 5 days late for AF, took a test the day I was due AF and also when I was 2 days late.

Didn't check for ovulation this month.

Tonight after sex there was some brown discharge and 2 tiny pink spots but in the hours since nothing on the tissue at all.

No symptoms or anything other than extreme fatigue but that's not abnormal for me 🤣

Is this AF coming later or possibly implantation. And assuming AF doesn't show...when do I retest?
