"i am 27 and i have been on nexplanon since february, so almost 4 months. the first three weeks was really annoying. i had ongoing light bleeding the whole three weeks, but then it just stopped. i have had no spotting and no period since and no side effects that i can say are definitely from nexplanon. i have had some unusual acne, but nothing crazy just an extra pimple here or there - it&#039;s probably more odd because i can&#039;t tie it to a cycle since i have no period. i have had a couple of headaches, but nothing that wasn&#039;t cured from excedrin migraine. all in all - it&#039;s effective (not pregnant) and i have no period (awesome!)"
