"i got the implanon in april 2010. i wasn&#039;t numb enough so it really hurt. the first 2 months or so were okay. no negative changes, very light spotting for a couple of days a month. around month 3, i started gaining weight, became very moody, and stopped being interested in sex. it got worse and worse, and after gaining 30 pounds and becoming completely frigid, i had it removed at month 7. this was 2 months ago, and i still have not lost any weight, and my sex drive hasn&#039;t increased much. the only good thing about this method is that once it&#039;s in, you don&#039;t have to remember anything for 3 years."
