"i had my implanon inserted september 17th 2012. before that i had a baby june 30th 2012. so im not so sure as to if i have gained weight from this product or from having a baby or even if it&#039;s from one or the other and im just overweight.  anyways i had it removed in february this year 2015. i have to say this is a great form of birth control.  never got pregnant on it. that was the whole purpose of having it inserted. the reason i decided to have it extracted is due to possible weight gain, mood swings, no period at all, and i did have a lower sex strive. since i had it removed my mood swings got better,  i have more of a sex strive which i didn&#039;t think it was decreasing, and i didn&#039;t start my period till after i had my paragard inserted."
