"i was on nexplanon for 2 years. the first couple of months was fine. i had regular periods; they were light, lasted 4 days, and no cramps! after the first couple of months my periods started to be irregular, severe cramps started. my period lasted 3 weeks, i&#039;ll be off my period for a week then it&#039;ll start back up. i had bad mood swings, i was always depressed and unhappy. i gained over 30 pounds within 2 years. i tried going to the gym/fitness center 5 times a week. that didn&#039;t help. i wouldn&#039;t recommend this bc. the only pro for this bc is that i never got pregnant while on it."
