birth control
"I got the implant in November. Bleeding was expected. I'ts now June and I am ALWAYS bleeding. I've been sticking it out for 8 months now hoping my body will cope with the new medicine. Looks like its not happening. I just got done bleeding for almost a week 3 days ago, went to the bathroom because of cramps and of course there was blood. 
As far as it actually protecting against pregnancy I wouldn't know because my significant other passed away a few months after a minor procedure. This thing sucks. I would never recommend it to anyone."
