birth control
"I have been on Implanon since May 2013 and altogether I have been on my period for a total of 6 months. My periods used to be super light and 3-4 days long. I have not gained any weight however I have lost all interest in having sex.  My boyfriend of a little over a year and a half is going crazy and I am also. I have read some other reviews on it and am glad I am not the only one. I will wait a full year before deciding weather or not I am going to take it out."
