Nexplanon
"I've had the nexplanon implant for about a year now and I have mixed feelings about it. Yes, it worked great in the aspect of me not getting pregnant, however I did gain about 20 pounds since getting the implant.  It's also made it almost impossible for me to lose any weight, I've been exercising, eating healthy, etc. At first I would get a lot of headaches but they've died down now, and I've also been very "gaggy," any little smell, texture, or sight of something gross makes me gag a lot. The one thing that's been keeping me from having it removed is the fact that I only get my period about 3-4 times a year. I used to have very painful cramps and heavy bleeding but since getting the implant my periods have been a lot lighter."
