"implanon is the easiest form of birth control out there, in my opinion.  you don&#039;t have to remember to take a pill everyday or even do anything on a monthly basis. i got implanon inserted in july, while i was on my period and it became effective after i was done with my period. i had it for only 2 days before i got married and it is working because i am not pregnant. i have not noticed any side effects other than my periods only come every other month and last for 2-3 weeks at a time, but the flow and cramps are really minimal from what they used to be.  no weight gain, mood swings or anything else. i recommend implanon to everyone looking for a birth control. i will never use anything else."
