"my implanon was inserted 4 months ago. at first i loved it. it was practically painless to have put in, i did have a little bleeding but not much, no weight gain at all. however, in the last month or two, i have had serious mood swings, crying spells, and have been extremely sad. i thought this may have been due to stress, but after reading many of these reviews i feel my moods may be due to the implanon. they are unbearable. i am sick of being sad all the time and it is causing problems with my relationship with my boyfriend. besides the major mood changes, implanon was good for me."
