Implanon not working??

Emma
Has anybody had the implanon bar and it stopped working before the three years was up?? Mine is due to come out in March and the past couple of years I've bled 24/7 (mostly just spotting nothing serious) but for the past week I haven't bled at all. I'm just nervous it's stopped working..I've read some stories online but would like to hear from someone who's personally experienced it. Thank you!
