What is wrong with me???

Tia
So I'm out again and a year and 7 months and I was thinking about the fact that I have brown and pink spotting for a few days before every period for as long as I've been off bc. But I only really took note until I was TTC and so I couldn't totally be sure when it started. Anyway my question is did anyone have this and know what it is and if it could be causing my issued with TTC?
