Etonogestrel
"I got the nexplanon in June 2014. It works as in I haven't gotten pregnant, but I'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'd like to know if anyone else has had this experience. I guess you should consider my period regular, but it sucks bc I'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't have to get a needle stuck in my butt and I don't have to remember to take a pill everyday and I'm still not pregnant so yaaay."
