"implanon has been a horrible experience for me. the only reason i have not had it removed is because i already have 3 children, all pretty close together and i&#039;m not in any hurry to have another one. i got implanon put in in december of 2010. the initial insertion was easy. now i have not had a period since, and even when i do it is very minimal. i have gained 30 pounds on it and have horrible mood swings, exhaustion and fatigue.
