What’s going on?

So, ladies I need some help, this is kinda a gross one, i got the implant 3 months ago and it’s really kicked with my period, this may be old blood but I get dark brown discharge- a lot of it and i really don’t like it, could anyone tell me what it could be and if I can prevent it xo, I wash everyday and stuff like that so I don’t believe hygiene is a problem- I can add a photo if needed but didn’t wnat to gross you out too much xxx
