"i have been on nexplanon for about a year now. at the very beginning i had huge food cravings. i did not have a period for about 2 months. then for about a month it started to regulate but it was very heavy. it has been 5 months now and my period has not stopped. i&#039;ve also gained weight even though i&#039;m incredibly active. i went from 135 to 148 now. my mood swings are insane! i have severe anxiety and depression. overall nexplanon is doing its job and i am definitely not pregnant but there are huge side effects of using this implant. i do not recommend it."
