"your body will either love or hate the implanon. i had the implanon for one and a half years, and for me it was bad. i gained 5kgs, and would go through these cycles - two weeks on, two weeks off - of non-stop bleeding, mood swings that nearby altered my personality, and a huge increase in anxiety. i actually thought i was mentally unwell, and my doctor was so reluctant to take it out, over and over again convincing me to keep it in. but then i insisted on switching to yaz, which worked beautifully with my body- i am myself again, losing weight was easier (i&#039;m back to my usual weight) and my cycle is back to normal.
