"okay y&#039;all, so i got nexplanon inserted in october 2015 and have been very disappointed with it since then (aside from its effective in preventing pregnancy). 
i am a very passive and understanding person, but in december i noticed my mood was literally all over the place. i have experienced a terrible bit of anxiety while using this product, and i have never had anxiety even in the most minor form before. i am sensitive to everything, crying, depressed, anxious, you name it. 
if you thought that was bad... i have had my period since the day i got it. yup, almost 4 months straight now. 
this is by far the worst birth control i have ever taken considering the side effects. it has made me feel mentally unstable and i do not recommend it."
