Brown discharge

Hey ladies!!

I need some help, i’ve had the implant for almost 2 months now and haven’t had a period on it - however, I’ve been experiencing some brown discharge and I don’t know if it’s something to be concerned about. I’ve had 2 UTIs in the past month, I’m not sure if that’s something to do with it... could this be considered my periods? is it just due to the new hormones entering my body? I also read that it could be from implantation - my boyfriend finishes in me, since I have the implant and I know the implant is 99.9% effective so I’m not too worried about this but PLEASE HELP IF YOU HAVE ANY IDEAS ABOUT WHAT THIS COULD BE!

Update : there is sometimes a pink tint to it when I wipe
