"nexplanon hasn&#039;t been the worst. i have no worries about getting pregnant, it&#039;s easy and it&#039;s comfortable. that&#039;s the best part-it works! but there&#039;s pros and cons to everything. i&#039;ve been on this for 9 months. i get a period every month, usually lasting for 2 weeks and the cramps are bad. i&#039;ve definitely noticed my skin worsen, i also agree with other reviews about the mood swings. nothing too crazy, but noticeable. my sex drive is sometimes effected, but no weight gain. i&#039;m going to give it a year to get it together, but i&#039;m looking forward to having it removed."
