The most common side effect of NEXPLANON is a change in your normal menstrual bleeding pattern. In studies, one out of ten women stopped using the implant because of an unfavorable change in their bleeding pattern.

The implant may not be placed in your arm at all due to a failed insertion. If this happens, you may become pregnant. Immediately after insertion, and with help from your health care provider, you should be able to feel the implant under your skin. If you can't feel the implant, tell your health care provider.
Removal of the implant may be very difficult or impossible because the implant is not where it should be. Special procedures, including surgery in the hospital, may be needed to remove the implant. If the implant is not removed, then the effects of NEXPLANON will continue for a longer period of time.

Ectopic pregnancies can cause serious internal bleeding, infertility, and even death. Call your health care provider right away if you think you are pregnant or have unexplained lower stomach (abdominal) pain.
Cysts may develop on the ovaries and usually go away without treatment but sometimes surgery is required to remove them.
