Etonogestrel
"I've had nexplanon implant for two and a half years. It wasn't so much a bad experience, I've had my period every couple months for at least 2 weeks. Just recently my period has lasted me about a month. Not necessarily heavy but really annoying. When I first got on nexlpanon I weighed about 125 - 130, and now I'm around 110. I've tried everything I could to gain weight from eating more to taking mass gainers. My body feels extremely weak and I'm always tired. I feel as if it's been getting worse."
