Ovulation spotting or something else?

Okay. So. I started some vvvvv light spotting the day after predicted ovulation. It’s was very light pink and only when I wiped. So I looked into it thinking it was some ovulation spotting.(I’ve never had it before) and everything on google said it’s only supposed to last a day or two. However now 4 days later it’s sometimes a very light brown but just super watery in my underwear or a v light pink when I wipe. I’m NTNP so I first thought that maybe it had something to do w pregnancy or something but that wouldn’t make sense. So now I’m at a loss as to what it could be. Is it normal? Or could it still be O spotting? I just go by the app I don’t do any specific methods of tracking. My cycles are also very very regular with never any spotting in between.

Also, I can’t go to the doctor to get things checked because I currently don’t have health insurance and can’t afford it.
