Does implanon help lose weight

Before I was on implanon I ran 5 days a week and lost weight super fast and easy but when I got on implanon in Nov 2010 I put on weight & couldn't shed the pounds! I eat very healthy & run 3 miles six days a week and still nothing for me implanon has made it difficult to loose weight but then again I love implanon because I haven't had my period since Nov but I will probably have it removed and try another Birth Control but everyone's different you could get on implanon and loose weight but it depends on the woman (:
