"i&#039;ve had implanon for about 5 months now, and it is been extremely effective so far. as far as the effectiveness, i would recommend it to anyone. but as the other comments have said, side effects are different for everyone. when it was first inserted, i had the worst period of my life for about two weeks with extreme bleeding and blood clots. i haven&#039;t had a period since then, but i have had spotting almost every day, which is extremely irritating. my main concern is not the current side effects, but the effects after removal.
