birth control
"I got my Implanon inserted on June 30th of this year, on the last day of my period.  I may have spotted for 2 days after about 15 days of having it.  However, it is now October 20th and I have not gotten my period yet, no bleeding or nothing, and I am not pregnant.  I may have gained about 5 pounds, but I won't blame the Implanon, I have been bad with my eating habits.  I have not gotten acne, or cramps, or moods or anything, although I may have a little headache once in a while, but nothing else."
