"i have had the nexplanon for 7 months now, it has been the most effective birth control i have used, compared to the iud and birth control pills. i have 4 kids due to the the failures of other birth control methods, they were used 100% as directed by medical doctors. 3 months after getting the nexplanon i stopped all periods, but still had all the cramps and side effects of a period. not the best feelings."
