birth control
"I had implanon inserted in July 2009 and chose to have it removed in January 2011. About a year (the 1st year was GREAT) after having this birth control, if there was a side effect I had it. From weight gain to month long periods with only a week in between. All side effects include acne (which I only had at the beginning of a menstrual cycle before), hair loss, bad mood swings, depression, weight gain, migraines, stomach problems, excessive bleeding. Try it out and if it works for you then that is great, but if after a while you notice side effects, pay attention."
