"i have been on nexplanon for a while. during the beginning, i had my period on my normal time of the month. after my first year, i had begun barely having a period. i don&#039;t know if it&#039;s diet or something, but i&#039;m on my second year and i have begun having my period for a month at a time, but three months without one. overall, i&#039;m not pregnant, and it hasn&#039;t effected my mood, craving, acne, anything."
