birth control
"After 5,6 months of implanon I gained 15 to 20 pounds.  It is extremely hard for me to lose even a pound I joined a gym but after 3 months of going at least 4 times a week for 2 hours and no results I tried cutting back calories and nothing! Its very depressing  because I'm not happy at all with my body and I feel so fat and terrified of gaining more. Even if I take it out it can take a year for your body to be how it was before I'm so stressed out and don't know what to do."
