Bleeding in between periods?

Has anyone struggled bleeding between periods ? Let me explain my situation. My problem went away and just came back this cycle basically my period last around 6 days. Around cycle day 10 I start pink spotting this is the day that glow says I enter my fertile window. By cycle day 14 (most fertile day ) the blood flow seems a bit heavier. At the end of my fertile window there’s no more bleeding. I’m TTC but how Can I if I’m always bleeding during my “fertile window “ I made a appointment. Just wanted some feedback ?

I never tried any opk test or anything. Not on any medications or anything.
