First time Ive ever had this what do you all think?

Past 3 days ive had small amount of brown CM any time I go to the bathroom its on the TP. AF isnt due for 3 days and I am never early.. usually late actually. Im not having the horrible cramps and leg aches like I always do. When AF shows up I always have an extremely heavy flow also. Lots of creamy brown and sometimes milky CM? I tested today and BFN..
