birth control
"I am 23 years old, and I have had the Implanon for almost 3 years. I will get it exchanged next month. I have not had any terrible problems. A year or so ago I had a light period that lasted for at least a month.  I usually have a light period of 3 days about every month. It has not caused me bad moodswings or any weight gain.I do eat healthy and walk. Overall, it has been great and prevented pregnancy! I recommend it to my friends."
