"i&#039;ve been on nexplanon for a few months now, and i love it! i&#039;ve had no periods and no spotting. it obviously does its job preventing pregnancy, but it really helped my terrible pms cramps. no weight gain, no acne. the only thing i will say, i have had my share of mood swings and depression moments (although i&#039;ve had depression prior to bc). being 99.9% effective is worth any side effect."
