Etonogestrel
"I had my daughter in March 2015 and I've had the nexplanon for about a month now and so far I love it. The first few days were rough, my arm would feel like the muscle strength would randomly disappear sometimes and there was a day where I had a few hours of morning sickness like nausea. Neither of those side effects have lasted, and I am back to feeling like myself and have actually lost weight! I've gone from 149 to 129 in a month! I haven't had any signs of a period yet which is great for me because my periods are terrible. The only other strange symptom has been two cystic acne like pimples at my hair line that wouldn't go away but I just checked and those have disappeared so I am VERY HAPPY with my decision to get the nexplanon!"
