I had the implanon inserted 3 years ago. After 1 and a half years I had it removed due to excessive weight gain. Or so I thought. A recent ultrasound showed that the doctor actually broke the impalnon on half and assumed he had taken it all out when he preformed the removal. I have since had the other half removed by a surgeon. My question is, even though there was only half an implanon in my arm, does it still work as a contraceptive? As me partner and I have had unprotected sex for the past 2 years and I have only had half an implanon on my arm. My other question is, how long after removal should I begin to start ovulating again??and when will the hormones from the implanon fully leave my body/system??
Hi, Implant is a progestin only demo contraceptive, the dose available being sufficient to avoid ovulation, so it was effective in your case even half size. It could do so because,  Implant has three-fold contraceptive effect, It acts by- avoiding ovulation Making sperm activity difficult by thick cervical mucus.  Making implantation difficult After removal of Implant, normal ovulation mostly occurs in six weeks time. Fertility returns to what it was before Implant insertion.  Thanks
