Spotting cd16

I have a question ladies, yesterday I had my annual pap, and I spotted for 1 hr after it. ... very light.

Then today, in the afternoon, I have light pink/brown discharge on my panties.

I'm only on cd16, I can't imagine it's af already. I had sex the day before O per the glow app.... that was 3 days ago.

Any idea on what this bleeding is? Ovulation spotting, maybe o'd late or early implantation and o'd early?

Haaalp lol
