"i got the implant in october 2 months before i turned 18. those 2 months were horrible. nonstop bleeding, cravings, hunger, moodswings, everything. after that&#039;s i still had the mood swings and hunger. my periods would come twice a month but it was light spotting and only lasted about 4 days. i did gain weight but it was only because i couldn&#039;t control the hunger that was cause by the nexplanon. it&#039;s the first of june and i haven&#039;t had a period in 3 months, my skin is clear, and i&#039;m not pregnant. everyone&#039;s body is different and the side effects are different. other than that this is a very effective method of birth control."
