"i got nexplanon may 9th 2014, insertion was quick and painless my arm was bruised for a few days but didn&#039;t hurt at all. the first thing i noticed was that i was hungry 24/7 and a little emotional also i got i little constipated. didn&#039;t bleed or spot till when my period was supposed to come and it was not a regular period it was much lighter but i did get bad cramps. i was bleeding for a week and then it went away. no headaches, no weight gain, no nothing! i love my nexplanon and i hope i don&#039;t get side effects later on!"
