"i have had a great experience with nexplanon. i have not experienced any side effects at all. i&#039;ve actually lost weight since i&#039;ve been on it. yes the arm was bruised for a few days but that went away fast. it&#039;s way better than getting pregnant! i&#039;ve spotted for a short period of time and did not experience my period the first month. i&#039;m in heaven with it. painless procedure, didn&#039;t feel a thing."
