Etonogestrel
"So, after having the implant for 8 years. Yes that's right, I've been crazy enough to have this 3 times. was fine at first. Then I started getting depressed, gained 7 stone throughout the years I have had it (on and off by dieting), depressed, unmotivated, tearful, low sex drive, acne, I've got severe acne scarring on my back, face and chest and even feeling suicidal at times and constant, heavy painful periods. The only reason I have had it as long as I have is because I heard horror stories about other forms, and I am forgetful so pill is not suitable. I've decided to pluck up the courage to get the IUD and finally say goodbye. THANK GOD! Can finally get my life back hopefully!"
