"i have been in nexplanon for a year. i love it!! during the first few months i had some bleeding for up to 3 weeks in a row but the flow was really light and it didn&#039;t bother me that much. i knew my body needed time to adjust. after that i had periods every 3 months for less than 4 days. no pain at all and really light flow. gain some weight but i haven&#039;t been watching my diet so i can&#039;t blame it on nexplanon. random mood swings but nothing severe or that i had to worry for. i have no secondary reactions in the implant site. just a little bit pain during the first month. overall i had a great experience. i love it."
