"i had nexplanon for 6 years total, i have mixed reviews on it. it was extremely effective at preventing pregnancy, and i didn&#039;t have periods at all while i had it! my only negative points would be horrible weight gain during the duration of having it and the weight was near impossible to lose. i recently had nexplanon removed and immediately experienced mood swings and drop in my sex drive. hopefully after my hormones rebalance i will feel normal! other than that, no complaints! definitely recommend for someone who does not want children for 3+ years"
