"i got the nexplanon in june 2014. it works as in i haven&#039;t gotten pregnant, but i&#039;ve had plenty of scares because after over a year my period is still irregular. it started off great, only got it once a month and it was shorter than normal. then at the beginning of this year i started missing 2 months of my period and then on the third month i get it twice as long. i&#039;d like to know if anyone else has had this experience. i guess you should consider my period regular, but it sucks bc i&#039;m in pain for so long (the implant has not reduced my cramp severity). another con is that it itches all the time. but i don&#039;t have to get a needle stuck in my butt and i don&#039;t have to remember to take a pill everyday and i&#039;m still not pregnant so yaaay."
