"i&#039;ve had the nexplanon for about 3 months and i love it. i still have my period but it only lasts about 3 days. i don&#039;t have mood swings, weight gain, etc. the only thing that happened to me was that my arm was bruised for like 4 days after i first got it implanted. sometimes i even forget about it because it just doesn&#039;t cause me any problems. i love it so much that i talked my roommate into getting it and as far as i&#039;m concerned, she doesn&#039;t have any problems with it either. i guess it just effects everybody&#039;s body differently."
