"i love my nexplanon! i was worried because of all the bad reviews i saw and the horror stories of weight gain, mood swings, and acne. i have had my implant in for a month now, and have had no bad side effects other than my light acne returning. i was on a pill that cleared it, but now that i&#039;m not, it&#039;s back. i have had no mood swings, weight gain, or bad spotting. i did spot for a week or two after first getting it, but it was brief. insertion was a breeze. overall, i would recommend trying this if you&#039;re looking for an effective method! worst case scenario, you have it taken out."
