"i am 20 years old and have had the nexplanon in my arm for 2 years.the insertion itself wasn&#039;t bad, just a little sting. i didn&#039;t have any bruising and the rod is still able to be felt in my arm.i first experienced a little acne and a little weight gain but nothing major. now having the rod in my arm for 2 years, i have experienced major anxiety, depression, and mood swings.as most other young adults, working parttime and going to school parttime can cause a lot a stress on a person.. at first i thought it was normal and every other person was experiencing the same stress as me.. it kept getting worse. my boyfriend of 3 years began to notice my changes. i have became completely depressed. i am now looking into getting my rod removed asap"
