"i have had nexplanon since june 2016. the first couple of weeks was perfect, but after i started feeling nauseous, dizzy and anxious all the time. i cannot stop sweating and had bad cramps during my period. i went to the hospital last week and have been told it&#039;s the side effect of the implant, therefore i ll get it off next month, but don&#039;t know how will survive all these side effects until then."
