Implanon, brown discharge help!!

Renee • 🌟🍂🌸☘️🍁💐🌻
I got my implant implanted on the 26th of Febuary this year, I had just finished my period and for about 2 weeks I was fine no discharge no nothing and then I just started getting light dark brown discharge? Is this normal?? Is there anything I can do to stop it it's putting me off my sex life because I'm too scared incase I start leaking out this brown discharge while it's happening ???
