BROWN DISCHARGE HELPPPP PLSSSS

SPEEY FOR THE PICTURE IN ADVANCE 😖 so my periods normally erratic. the last time i had a cycle was september 17th and it's going on december 27th with  i sign of me having one anytime soon. i tested for pregnancy 3 times already and they were all negative. i had this discharge a couple months ago and no cycle so i thought it was just my old uterine lining. this month i have slight cramping also but no other signs of a period now i am starting to get worried... i haven't been to the doctor yet. i go next week.
