"i got my nexplanon insert in december 2015- 5 months later and i wish i did not get it. i have crazy moods swings and get depressed for no reason. i have gained almost 10 pounds and workout 3-4 times a week. although this form of contraceptive does its job of not getting you pregnant, i wish i researched more about the side effects. when i first got nexplanon i spotted for 2 months and after that i haven&#039;t had a period since the end of february. i do not recommend getting this insert!"
