"i am on implanon right now. i haven&#039;t gained weight no mood swings just my normal attitude and i haven&#039;t gotten my period for like a year and a half and love it but i came here to find out if that was normal. i have been having some serious cramps that don&#039;t feel like period cramps or even close. they are a little higher and might be something very painful like something to do with my gall bladder but i have to ask around without going to a doctor. i don&#039;t like going to doctors."
