I was on the implanon for 3 years. It will be 2 years in February that I've not had any birth control. I've had unprotected sex for the past 2 years and I can't seem to get pregnant. Me and my fiancé have really been trying and I'm wonering if the implanon has anything to do with it. Is there anyone out there that has got pregnant after it? And if so, how long did it take? Kristin
