Etonogestrel
"I absolutely love Nexplanon. I got it inserted in July 2013. Since then I have one extremely light period that lasted two days. I have no experience weight gain. I have always had very little acne and Nexplanon did not cause my acne to increase. I also haven't experienced a changes in moodiness. I recommend Nexplanon to my friends all the time. I also have a friend that has it and she really likes it although she has experienced some weight gain. I am very surprised so many people have had such a terrible experience. If you are considering getting Nexplanon do not let these horror stories scare you away. Everyone has a different experience so you'll have to see if it's a good birth control option for you."
