### input:
I have had the implanon in my arm and it has expired, its expiration was in February. But due to no insurance and keeping a busy schedule I havent had the time nor money to have it removed. I was just wondering if I can get pregnant now? I feel as if I am, but the test come out negative. Im also worried I might become infertile. Help?

### output:

Hello, and I hope I can help you today. Even though there is an expiration date on the Implant, for medical safety and medications are devices that expire still have some function in them beyond the expiration date. So there is a very strong possibility that if you are not menstruating your Implant is actually still providing contraception. Furthermore, the side effects of the Implant can be similar to pregnancy, as the hormone in the Implant in certain ways tricks your body to thinking that your pregnant in order to provide contraception. So at this time, it is most likely the Implant is still preventing pregnancy. Eventually, the usual way you will find out that the Implant has worn off is that your menstrual period will begin again. However, if you strongly do not desire pregnancy I suggest you use a backup method of contraception just in case. There is no reason to believe that you are infertile while you on birth control. Until the birth control is completely out of your system, there is no way to know about whether you can conceive. If you are otherwise healthy and under the age of 35 and at regular menstrual cycles before you got the implant, there is no reason to suspect that you would have problems with fertility once the birth control is out of your system.  The rod should be removed when you can, as the device was not tested for integrity in your arm much beyond the expiration date.  In the United States, Planned Parenthood offers low-cost and free birth control management and would be a good place to investigate for removal of your Implant at an affordable rate. I hope that I was able to adequately answer your question today, and that my advice was helpful. Best wishes,
