"if you&#039;re thinking of getting nexplanon or any other birth control for that matter, i want to warn you most people on the internet exaggerate a lot. as for my background i&#039;ve had the mirena iud and nexplanon. i&#039;m 18, never been pregnant. nexplanon has been good for me insertion was painless and quick. as for side effects, i&#039;ve just had a little bit of acne but nothing major and i&#039;m not even sure it&#039;s a side effect from the implant. i&#039;ve lost a few pounds since getting nexplanon because it does suppress my appetite quiet a bit ( from 125 to 118) the first couple days after insertion i was a little nauseous and couldn&#039;t really eat. other than that nothing else has changed and i&#039;m not pregnant so that&#039;s good."
