"the worst birth control option available. i had nexplanon in my arm for six month, and those six months were a nightmare. i suffered terrible anxiety. i also started having problems with lactose temporarily and questioned if i was lactose intolerant. i would randomly cry when i was alone. it sparked adult acne. i had trouble breathing sometimes. honestly, it was just a horrible, confusing experience. sure, it is effective in the sense that it prevents pregnancy, but there are better options than nexplanon."
