"nexplanon was the worst birth control i&#039;ve had. i got it implanted on march 1, 2016. after a few weeks all of the bad side effects started to occur. i was confused all the time, gained 8+ pounds in a month while eating healthy and exercising, extremely tired, depressed mood, and the worst side effect: i felt as if i was living in a low blood sugar state at all times. after reading reviews, some say they need to snack every 2-3 hours to not feel dizzy... at that point i would rather not have the implant at all. got it removed may 28th and it was the best decision i have ever made. most of the symptoms have subsided, waiting to get another set of blood work done 2 months post removal for my pcp."
