"everything affects everyone differently. with that said i have had the nexplanon for just over a year and i&#039;m not loving it. i had the mirena for 5 years. no issues and period was very light. 5 years is the max then you need a new one. my doctor who inserted the first one couldn&#039;t get the replacement in.  so moved to plan b. my doctor mentioned nexplanon because i didn&#039;t like pills or nuvaring. insertion was easy and pretty painless. they use a local anesthetic.  my doctor thought i would react in a similar manner to the mirena but that hasn&#039;t been the case. my skin is oilier, it breaks out, and my period is much heavier. not to mention i gained 10 lbs. probably will get it removed once i decide on another option."
