"i got nexplanon inserted november 2014. my fella and i have never used standard protection and we&#039;ve never gotten pregnant, in nearly 3 years. so, good there.  however, this birth control is horrible. i am healthy, i eat right and workout consistently, for years. i&#039;ve gained 30 pounds since nov 14. i&#039;ve upped all of my workouts to 3-4 hours, 4+ times/wk with zero change. i&#039;ve never been had such extreme bouts of depression in my life. if not for yoga, meditation and my sweetheart of a fella, i&#039;d lose my mind. i&#039;ve spent a ton on pregnancy tests due to the whacked out side effects, including randomly missed periods. my periods are horrible: cramps, random cycle lengths, never 28 days apart and random spotting. the side effects are horrible."
