"i&#039;ve been on liletta for a year now. if you never had children like me you will find the process very painful. i had severe cramping for about an hour after insertion and slight bleeding over a couple days. my periods are very light now basically spotting, but they last longer.  my acne has not changed; i still break out around the time of my period. and i feel like this iud might be making me put on weight or not helping me to loose it. overall very effective to prevent pregnancy."
