Ovulation bleeding or other?

Jenn • 💕 pregnant with baby #2 🤰

Currently on CD17 - I have PCOS but lost a bunch of weight recently and my periods have become fairly regular around 28-30 days per cycle.

BD on CD 12 and 15 - yesterday I had a faint streak of blood later in the day. Earlier this morning I had one time of bright red spotting (didn’t think to take a pic) and then this just now.

I haven’t been good about tracking with OPK so I don’t know when I ovulated or anything like that… we aren’t TRYING yet, just not preventing and I’m trying to learn how my body works since it’s becoming more regular.

Is ovulation spotting a thing? Or could it be something else? I feel like it’s too soon for implantation bleeding.
