Etonogestrel
"I'm 18 and I got my Implanon inserted about a month ago. I got my period which was 4-5 days long. It was very light and I had no pains. This was great for me as I usually suffer with heavy, VERY painful periods but the downside to this is I have been getting very emotional and moody lately. I'm hoping this will wear off soon as it can get in the way of things but I still have a long way to go so hopefully it will all work out for the best."
