I have had Implanon for 4 years, and now currently on Nexplanon since September of last year (5months). I have been bleeding non stop, maybe with a 1 or 2 day break but then it gets right back to it. Now, I know this happens with a lot of implant users but recently I stopped bleeding. It's been a month, with few spotting days maybe 3. I think it may have ran its course and finally I stopped bleeding for good. Fingers crossed!! It only took 4.5 years haha.
