"this is effective in preventing pregnancies, but i&#039;ve had some other unpleasant side effects. i&#039;ve been on this for 9 months. during the first three, i would always break out real bad around the time of my period. then for a couple months, the acne stopped, but other symptoms began popping up: spotting, sometimes early period, extreme mood swings, weight gain (20lbs). the last two months, when my libido began to suffer, i decided to switch. no sex drive. none. it&#039;s killing me. even if i want to have sex, which is rare anyway, my body says no. the end of this pack is it for me."
