birth control
"I have been using implanon, now nexplanon for 5 years now. (3 years each) this is my second insertion after my first was expired. Since then I haven't had my period in ages. However, my appetite had taken full control and weight gain came along. Sex drive has slowed down and mood swings here and there. So yeah things u will have to work on. Still..no pregnancy at all and no periods. Its like an extended vacation from mother nature"
