Etonogestrel
birth control
"I wanted to share my experience with Nexplanon. I got it inserted February 2014, after being on the pill for 3 years. I thought I would get rid of monthly cycles, but I was wrong. I had a little spotting for 2 weeks post insert and then nothing at all for 4 months. The 5th month and up until  today, my cycle starts with cramps, fatigue, and nausea like it would normally if I weren't on birth control and the bleeding is light and lasts about a week. This is quite annoying, but I'm glad it followed my usual cycle so I've actually gotten to the point where I'm used to it now. I haven't gotten pregnant, so I'd say the implant works! Figuring out what it will do to your body is the tough part."
