"i had implanon inserted in january 2009. it was my only choice, as i have heart problems that make it unsafe for me to take birth control with estrogen and a wacky fallopian tube that crossed the iud off of my list of options. the main reason i decided to get implanon was to stop my awful cramps each month. before implanon, was hell. vomiting, diarrhea and crippling pain. since insertion i haven&#039;t had a period or cramps. i&#039;ve experienced no negative side effects and will most likely have another implant once this one has run it&#039;s course. i highly recommend this birth control."
