Etonogestrel
"I had Nexplanon placed a month ago and so far it's been good. The procedure was quick and painless, lasted about 2 mins and I was done, it's not at all noticable in the arm it's placed and as far as side effects I've experinced the light spotting that started a week ago to date but it only requires a thin panty liner. During the first two weeks I was very moody and emotional with no libido but that has gone and my body feels it's regular normalcy. Once the spotting finally goes I'll be able to say it's great (hate the spotting) but rather spot than be pregnant and not having to remember to take a pill or suffer weight gain is a plus with Nexplanon, I've actually lost weight while on it so all in all I'm loving this contraceptive choice."
