"nexplanon was effective i am not pregnant. but the side effects are terrible. i am getting it removed in a couple days. i would have periods for at least a month or sometimes longer. i took nexplanon for a year and a half. i had some weight gain and no sex drive because i was constantly on my period. i just feel as if there are more negatives than positives with nexplanon. i wouldn&#039;t reccomend it. nexplanon prevents pregnancy but makes the user miserable."
