"after starting this birth control i had the amazing side effect of no period for six months. after that six month grace period had ended, i began to get my period once every two weeks, sometimes more depending on how often i had sex. also, it became a lot easier for me to gain weight once i had this implant. i gained 20 lbs in one year and am still working on losing it. my mood swings have been all over the board and i find myself feeling depressed and anxious more often than not."
