"i got implanon in march 2008 after having my first baby! i didn&#039;t start my period again until about 14 months after (probably more of a baby thing than an implanon thing). since i started my period again i go through phases..a couple of months of heavy heavy bleeding...and couple of little or no bleeding. i have not experienced any weight gain-- in fact quite the opposite. i constantly eat anything i want to, have no exercise plan (aside from chasing my crazy daughter around!), and keep losing weight. i haven&#039;t experienced any vaginal dryness or mood swings (other than what&#039;s normal..i&#039;ve never been all that stable). some headaches, a little lower sex drive, and no more babies! overall though i&#039;m very pleased with implanon."
