Etonogestrel
"My experience with implanon has been off and on good. I got my implant in July 2015 and in September I started losing weight due to diet and exercise. I eventually fell off with that then started gaining weight. So I cannot be sure if its the implant or not? My boobs were constantly sore with the month of October, that has gone away now. I had my period in August, and spotted a little in September but I have not had my period since which the doctor said was normal. I have had a lot of depressed symptoms, I am more sensitive now than I was before. But now I am getting use to it and just becoming more intune with my body. Overall I do like the implant, the procedure did not hurt, everything went well. So far so good for me :)"
