I had the implant inserted almost 2 months ago. Once it was inserted I never got my period. About a month after having it in I noticed an odor. It smelt kinda fishy and was followed by brown discharge. The smell stopped 2 weeks ago. But I've had the brown discharge for quite some time. Yesterday it came out bloody but very light kind of in a mucus when I first wiped but then through out the day it was brown. I have to put a tampon in because it gets all over my underwear. Should I be concerned? Is this normal?
