Thoughts/Advice PLEASE!

Still TTC #1..

Had some spotting yesterday (8dpo) light pink. Then when I woke up this morning (9dpo) it got heavier like a light period but then it got much lighter like yesterday’s spotting right away, and has stayed the same for hours now but only when I wipe nothing got on my underwear ladies for when I woke up as well. (Usually my periods are super heavy and messy!) I’m very confused right now what this could be? I know it could be my period or could it be implantation bleeding?

I’m currently 9dpo today! I didn’t track ovulation or anything this cycle. My app says I’ve ovulated the 27th but I also had spotting the 29th of December.. very confusing sorry!
