"nexplanon does its job. i can have worry free sex. the only thing is that my periods are sometimes light and sometimes heavy. sometimes they go away and sometimes they show up unexpected. i also feel somewhat depressed. not sure if its nexplanon or not. i&#039;ve had nexplanont for about 2 months now, but despite the side effects its the most effective birth control i&#039;ve ever used and i do not plan on taking it out."
