Etonogestrel
"When I first got the implanon I didn't stop bleeding so my doctor gave me a medication for a few days to help. Well it's been over a year and I still bleed every other week. I've gained some weight too but my main issue is the bleeding. It's such an inconvenience and I cannot wait to take it out. As a form of birth control it's very effective and I would advise it to someone who doesn't practice safe sex"
