birth control
"I had the Implanon inserted on July 24, 2009 and had a little bruising, but nothing too serious.  Two weeks later I had a very painful period, where I couldn't get out of bed, literally! My period usually lasts 3-5 days, and on Implanon it lasted almost 2 weeks.  No it wasn't spotting, it was still bright red blood.  But 6 weeks later, I am still spotting! I have changed my eating habits and work out 6 days a week, and have not been able to drop a pound! I have no sex drive either and have had more acne in the past 2 months than I have ever had in my life.  "
