"i&#039;ve had my implanon for 14 months now and love it. as a busy college student/newlywed i didn&#039;t want to have to worry about a pill or shot so this do it once and forget about it method works great for my schedule. positives: i&#039;ve had a great sex drive, absolutely no period or bleeding and no pregnancy. negatives: i have experienced weight gain and mood swings or i guess a heightened level of the moods i already had. i tend to cry for no reason at random times and get really short with people, which like i said, i did before the implanon. now it just seems a bit more common. i plan to keep mine the full 3 years."
