constant brown discharge 😭

I'm on the implant and i've had it for about a month and a few days now and this last 2 weeks i've had nothing but brown discharged. Some days it light and others it's not and I don't know what to do or if i can make it go away. It's not dried or old blood from a period because I got put on depo the 12th of september and haven't had a period since october so i don't know why i'm having all this discharge. Can I make it go away or stop?
