"i had the nexplanon inserted on december 2015 and i had to remove it a week ago on june 2016. i have tried a couple if different birth controls and i have to say this was the worst one for me. i have gained 7 pounds in 6 months when i have not changed my diet at all. i was also getting random headaches and a lot of acne on my face specially around my chin. i also started spotting a week after i put it in and it did not stop until a week after i removed it."
