Long brown spotting

Kalee

I have been having dark brown spotting for 10 days. It varies in flow of sometimes barely any at all through the day to like a medium amount. I have yet to fill up a pad, nor a light tampon. I have no period symptoms (sore breast’s, cramping, mood swings, etc). Is this my considered my “period”? Also my last cycle started May 15. I have been diagnosed with PCOS, but this is new. Help please!
