Etonogestrel
"I first got the Implanon after I had my son in 2011. It was great!!! I only had a period every 2-3 months and absolutely no other side effects. I got it taken out and another one inserted in September 2015 and everything was the same until September 2016. Everything changed. It started with my period but with that I became very nauseous, depressed, anxious, and worried. I was angry and upset and just wanted to stay in bed. Went to doctor and was given meds for depression and panic attacks but I knew something had to be the cause because I've never ever had these problems. I've had blood tests ran, Pap smear, and even ultrasounds on my Thyroid and abdomen. Nothing was found. After reading reviews on the implanon, it was removed last week!!"
