"i&#039;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&#039;s also made it almost impossible for me to lose any weight, i&#039;ve been exercising, eating healthy, etc. at first i would get a lot of headaches but they&#039;ve died down now, and i&#039;ve also been very &quot;gaggy,&quot; any little smell, texture, or sight of something gross makes me gag a lot. the one thing that&#039;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."
