birth control
"I'm 17 years old and my mom works at an OB/GYN office and had me get Implanon.  The only negative part was it bruised for about a week and my stomach was a little upset the next day.  I have gained no weight or have had my mood effected or any other bad side effects.  My sex drive is just as high as it has been.  I love it because I have not gained weight, I have light spotting to no periods and it's stuck in my arm so I don't have to remember my birth control daily."
