ruptured cyst or implantation bleeding?

I thought I got my "period" mid yesterday when I took a shower, I don't have bright red blood at all. it's more of a brownish. I'm 5 days early for my "period" as well, so I thought it was odd that I'm bleeding when typically I'm on a pretty good routine with my cycle! anyone gone through this?? I'm not bleeding nearly enough for my "normal period". I was also told not even a week ago that I have a cyst, however I'm not in terrible pain. I'm not in that much pain at all actually, not yet anyways. helpppp😩😭
