"i&#039;m currently 21 and i&#039;ve had nexplanon for just over 2 years now (since 15th june 2015) and have had absolutely no problems with it. possibly the best decision i&#039;ve ever made.
obviously all bc affects everyone differently, but for me i&#039;ve experienced no mood swings, i haven&#039;t had a proper period or cramping in 2 years now (i&#039;ve had maybe 4/5 occurrences of extremely light spotting in 2 years -lasting no more than a day each- and even that was mainly just slightly pink discharge), i haven&#039;t noticed any weight gain from it (but i was gaining weight regardless because i started university and lived off take-outs).
i&#039;ll be getting it replaced a few months before it&#039;s due just to be sure. i love it, though."
