What are the most common side effects I can expect while using IMPLANON?
The most common side effect of IMPLANON is a change in your menstrual periods. In studies, about 10% women stopped using IMPLANON because of bleeding problems. Expect your menstrual periods to be irregular and unpredictable throughout the time you are using IMPLANON. You may have more bleeding, less bleeding, or no bleeding. The time between periods may vary, and in between periods you may have spotting. Talk with your healthcare provider if you think you may be pregnant or if our vaginal bleeding is heavy and prolonged.
