Period or not??

Period or no?

I have always had irregular periods... most range from 5-8 weeks in between. I have been using glow to track and hopefully find a pattern. but this month has been odd. For the last 2 weeks I have had a very light pinkish or tanish tint to my CM as well as a few random days with dark brown or bloody discharge. It will usually only happen 1-2 times a day and is only when I wipe. Just wondering if I should count this as my period or not?? I have taken an opk everyday since my last period and all were negative. Took a pregnancy test today and it was negative as well. I just don’t know what to track! Any insight would be appreciated!
