"i am a huge fan of the nexplanon (formerly implanon) and am currently on my 3rd rod. if you have heavy painful periods like i do and cannot take a pill every day for whatever reason, this is the best birth control out there. trust me, i&#039;ve tried almost all of them. the trick, i think, is getting it switched out before the 3 year deadline. once you get to 2.5 years or so, your hormone levels get funky and you&#039;ll start having periods again. in the course of the last 7-8 years, none of my gynecologists have had any issues with switching it out early. there&#039;s no extra cost and it just makes sense. plus, most of the &quot;oops, i&#039;m preggers&quot; stories out there regarding the nexplanon got pregnant that last year. so, it&#039;s also better safe than sorry!"
