"i was on nexplanon for a year. i didn&#039;t have any major issues with it. it worked great as far as the birth control aspect of it. but while i was on it i started having a vaginal odor sometimes daily sometimes on and off. i went to the gynecologist and got a check up. all tests came back negative. they treated me for vaginosis just in case but no prevail. as soon as i got the nexplanon taken out the odor went away. other than that it was great not having to remember to take a pill. and i&#039;m not sure if it was the bc or not but i felt when i was on it my mood was like a rollercoaster. i&#039;m sure my bf noticed the difference but i went from depressed to happy to mad and sleeping a lot."
