is this normal? **didnt know where to put this post**

hi okay so i have this weird brown discharge that has been basically non stop, and it’s starting to get really frustrating. i started about a year and a half ago on the pill, but stopped bc i would sometimes forget it. after that i went a month on the depo shot, quit that because i didn’t like how much weight i gained and overall how i felt with it. i’ve been on the implant for months now and overall like it. however, i stopped getting my period while on the shot. & along with the implant. until the discharge started. i talked to my doctor about it and she said take another month of the pills, so i did. and the discharge stopped. then about a week ago i got my normal period. and right when that stopped, the discharge started again. it’s so frustrating to deal with. any advice?
