"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&#039;t get out of bed, literally! my period usually lasts 3-5 days, and on implanon it lasted almost 2 weeks.  no it wasn&#039;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.
