Implantation or ovulation bleeding?

Katy • PCOS & TTC baby #1.

I honestly do not believe I’ve ever had “ovulation bleeding”. App estimates I ovulate today, and I just got this when I wiped and there’s a little in my underwear. I had sex 4-5 days ago at the start of my fertile window. Is it too early for implantation bleeding? Sorry, newly TTC 😬😳
