"have had nexplanon in my arm for a little over a year now. no problems with the insertion. it is very effective. didn&#039;t use a condom. sex at least once a week and haven&#039;t gotten pregnant yet so thats why i give it a five star rating. side effects for me were slim in the first couple of months but soon after my mood definitely changed. i cry over everything now. i&#039;ve experienced mood swings, appetite increase and decrease, some days i can&#039;t stop ranting.  i have gone from occasional depression to depressed all of the time. can&#039;t sleep.  anxiety all day long. dizzy. fatigue all day. longer periods. never had anxiety attacks before, do now. they&#039;re becoming more frequent. getting it removed"
